pyinstaller .exe works locally but fails when called by C#?

I have created a script using Python2.7 and compiled it using pyinstaller into an exe of the same name, in this case "GeneralStats.py" turns into "GeneralStats.exe" using --onefile and -w arguments.
When called with C# I use:
var pythonDirectory = (Directory.GetCurrentDirectory());
var filePathExe1 = Path.Combine(pythonDirectory + "\\Python\\GeneralStats.exe");
Process.Start(filePathExe1);
When called outside of C#, so in my local files I can run the .exe and the result is a text file with lots of values in (Running correctly).
However, when ran with C# in this format, I get an error that "GeneralStats returned -1!"
Which I have had issues with before, but it was a simple python error that when I returned to my code and ran it, I would receive an error that I overlooked.
This time my python code returns no errors and works outside of C#.
Any ideas of why this could be? I can provide any code or file directories necessary, please just ask if you feel it would help with debugging.
EDIT:
Solved by removing:
var filePathExe1 = Path.Combine(pythonDirectory + "\\Python\\GeneralStats.exe");
Process.Start(filePathExe1);
And replacing with:
ProcessStartInfo _processStartInfo = new ProcessStartInfo();
_processStartInfo.WorkingDirectory = Path.Combine(pythonDirectory + "\\Python");
_processStartInfo.FileName = #"GeneralStats.exe";
_processStartInfo.CreateNoWindow = true;
Process myProcess = Process.Start(_processStartInfo);

You need to set the working directory for the Process - it is probably trying to load files from its working directory but isn't finding them.
See, e.g. this:
Use the ProcessStartInfo.WorkingDirectory property to set it prior to starting the process. If the property is not set, the default working directory is %SYSTEMROOT%\system32.
Set it to the path where GeneralStats.exe is.

Roslyn Scripting - Script without "System"

As of this article I want to write a little C# scripting engine to work. I have tried this code:
System.IO.StreamReader sr = new System.IO.StreamReader("example.txt");
var prog = sr.ReadToEnd();
sr.Close();
ScriptOptions so = ScriptOptions.Default;
Console.WriteLine(CSharpScript.RunAsync(prog, so).Result.GetVariable("sum").Value);
Console.ReadKey();
And the file content of example.txt is:
System.IO.StreamReader sr = new System.IO.StreamReader("foo.txt");
string s = sr.ReadToEnd();
int sum = System.Convert.ToInt32(s);
Now I want to restrict the user to only basic functions of C# (using int, string, while, for) and some self defined functions but NOT the whole .NET library. But even if I don't include System.IO als reference the user can type System.IO.something and will get the right thing.
Is there a possibility to remove the access to "System" from the script?
I'm glad with any answer.

You'll need to set up the ScriptingOptions properly, meaning that a custom MetadataReferenceResolver needs to be used instead of the default one, which is resolving the missing references automatically. I don't know if there is already a resolver that only resolves assemblies based on its parameters, but you can certainly implement yours. Check out the TestMetadataReferenceResolver, which does something similar.
Update
This won't work for things that are defined in mscorlib.

asp.NET c# : Code working as a console app but not as a web app

My basic problem was converting a .docx file to .pdf. The problem would be solved incase I was allowed to use Microsoft.Office.Interop.Word.dll, which i am not since the server will not have MS Office installed. So I needed a free/open-source library that would allow me to do so. And i came across docx4j.NET.
http://www.docx4java.org/blog/2014/09/docx-to-pdf-in-c-net/
This worked fine as long as I ran it as a Console App. The following is the concerned code snippet:
string fileIN = #"C:\Users\...\Visual Studio 2013\Projects\HRDapp\HRDapp\Letter_Templates\AP.docx";
string fileOUT = #"C:\Users\...\Visual Studio 2013\Projects\HRDapp\HRDapp\Letter_Templates\AP.pdf";
log.Info("Hello from Common Logging");
// Necessary, if slf4j-api and slf4j-NetCommonLogging are separate DLLs
ikvm.runtime.Startup.addBootClassPathAssembly(
System.Reflection.Assembly.GetAssembly(
typeof(org.slf4j.impl.StaticLoggerBinder)));
// Configure to find docx4j.properties
// .. add as URL the dir containing docx4j.properties (not the file itself!)
Plutext.PropertiesConfigurator.setDocx4jPropertiesDir(projectDir + #"src\samples\resources\");
java.io.File file = new java.io.File(fileIN);
// OK, do it..
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(file);
java.io.FileOutputStream fos = new java.io.FileOutputStream(new java.io.File(fileOUT));
org.docx4j.Docx4J.toPDF(wordMLPackage, fos);
fos.close();
In case of using this in a Web App, the code runs fine till
java.io.File file = new java.io.File(fileIN);
and gets stuck at
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(file);
Although the file path is correct and works fine in the console app, but there seems something else that I am missing here. The log also prints upto the following statement-
iisexpress.exe Information: 0 : [INFO] org.docx4j.jaxb.Context - Using Java 6/7 JAXB implementation
.. and stops. Any kind of reply directing me to the source of the error will be very helpful. Thanks.

As Jeroen (of IKVM fame) has explained, when there is no main assembly (eg in an ASP.NET application), the IKVM class loader can't find your assembly when the code is trying to dynamically load a class.
So you'll want to add not just:
ikvm.runtime.Startup.addBootClassPathAssembly(
System.Reflection.Assembly.GetAssembly(
typeof(org.slf4j.impl.StaticLoggerBinder)));
but also:
ikvm.runtime.Startup.addBootClassPathAssembly(
System.Reflection.Assembly.GetAssembly(
typeof(org.slf4j.LoggerFactory)));
ikvm.runtime.Startup.addBootClassPathAssembly(
System.Reflection.Assembly.GetAssembly(
typeof(org.docx4j.jaxb.Context)));

C# program connecting to example DBus daemon always gets 'Access is denied: DBus.BusObject'

For our current project we are using DBus (1.6.n).
It is largely accessed from C++ in shared memory mode, and this works really well.
I am now trying to access the same DBus from a C# program.
In order to try things out first, I downloaded the latest version of dbus-sharp I could find, and started the daemon included in the download to see if I could connect to it from my test C# app.
Whenever I make a connection, the daemon console shows that I am communicating with it, but as soon as I try to access any methods on the connection I get the error;
'Access is denied: DBus.BusObject'
Here is the code I have tried;
DBus.Bus dBus = null;
try
{
//input address comes from the UI and ends up as "tcp:host=localhost,port=12345";
//dBus = new Bus(InputAddress.Text + inputAddressExtension.Text);
//string s = dBus.GetId();
//dBus.Close();
//DBus.Bus bus = DBus.Bus.System;
//DBus.Bus bus = Bus.Open(InputAddress.Text + inputAddressExtension.Text);
//DBus.Bus bus = DBus.Bus.Session;
//DBus.Bus bus = DBus.Bus.Starter;
var conn = Connection.Open(InputAddress.Text + inputAddressExtension.Text);
var bus = conn.GetObject<Introspectable>(#"org.freedesktop.DBus.Introspectable", new ObjectPath("/org/freedesktop/DBus/Introspectable"));
bus.Introspect();
}
finally
{
if(dBus != null)
dBus.Close();
}
The commented code produces the same error eventually too.
I have stepped through with the debugger and it always gets to the following code in the TypeImplementer.cs;
public Type GetImplementation (Type declType)
{
Type retT;
lock (getImplLock)
if (map.TryGetValue (declType, out retT))
return retT;
string proxyName = declType.FullName + "Proxy";
Type parentType;
if (declType.IsInterface)
parentType = typeof (BusObject);
else
parentType = declType;
TypeBuilder typeB = modB.DefineType (proxyName, TypeAttributes.Class | TypeAttributes.Public, parentType);
if (declType.IsInterface)
Implement (typeB, declType);
foreach (Type iface in declType.GetInterfaces ())
Implement (typeB, iface);
retT = typeB.CreateType (); <======== Fails here ==========
lock (getImplLock)
map[declType] = retT;
return retT;
}
I have not found any useful examples or documentation about accessing DBus from C#, and there seem to be few recent entries about this anywhere, so maybe no-one else is trying this.
I am running the daemon in the same folder as the test program.
As I am running on windows, the daemon is listening on the tcp setting;
string addr = "tcp:host=localhost,port=12345";
Since this is the example included with the download, I thought it would be really simple to get it going, but alas no luck yet.
Has anyone else been here and know the next piece of the puzzle?
Any ideas would be appreciated.

Having received no comment or response, I will answer the question with the information I have found since asking it.
There appears to be no useful C# interface to DBus. (By useful, I mean one that works!)
The only information or examples I could find are not up to date and no effort appears to be being expended on providing a working interface.
I have decided to interface with DBus by using a C++ implementation written as a Windows service, and my C# program will send messages to DBus via the service. This seems to work ok, so satisfies the business need.
I am disappointed not to be able to get the C# to DBus working, but there are lots of service bus implementations that work on Windows, so in future I will look at implementing those instead of DBus.
If anyone does come up with a workable, documented solution to accessing DBus from C# on Windows, I would still be interested to see it.

I had the same error when I created new test project and add dbus cs source files to it main project assembly. It was when IBusProxy type dynamically created in dynamically created assembly.
asmB = AppDomain.CurrentDomain.DefineDynamicAssembly (new AssemblyName ("NDesk.DBus.Proxies"), canSave ? AssemblyBuilderAccess.RunAndSave : AssemblyBuilderAccess.Run);
modB = asmB.DefineDynamicModule ("NDesk.DBus.Proxies");
......
retT = typeB.CreateType ();
I think it was cause current running assembly isnt friendly for created assembly. And just when I add to project compiled NDesk.DBus.dll this error disappeared.

vmware .net api help vmware.vim.dll problems

Vmware's .net api reference is somewhat confusing and hard to follow. I have been able to connect to my vcenter host then get a list of esxi hosts. Then I have been able get all the running modules on the host using HostKernelModuleSystem, and probe the properties on the variable "mod"... but I am not able to figure out how to get license info, I tried creating an object lic below, trying all different kinds of "types" from vmware with the word license in the type. but, it never works it has a problem converting the line with LicenseManagerLicenseInfo lic = .... I always get the following:
"Cannot convert type 'Vmware.Vim.Viewbase' to
'Vmware.Vim.LicenseManagerLicenseInfo'"
but the declaration above it for "mod" works fine.
I have also tried:
HostLicenseConnectInfo
LicenseAssignmentManagerLicenseAssignment
LicenseManager
I am hoping someone who has worked with vmware .net api can shed some light on what i am doing wrong? I am new to C# about 1 year :) but these VMware APIs are somewhat confusing to me.
esxList = client.FindEntityViews(typeof(HostSystem), null, null, null);
foreach (HostSystem host in esxList)
{
HostKernelModuleSystem mod = (HostKernelModuleSystem)client.GetView(host.ConfigManager.KernelModuleSystem, null);
LicenseManagerLicenseInfo lic = (LicenseManagerLicenseInfo)client.GetView(host.ConfigManager.LicenseManager, null);
string name = lic.Name;
}

I'll have to go to work tomorrow to look at this ( don't have ESX and VMWare SDK for .NET at home ) but I've done a bit of this work.
I wrote a generics method that wraps FindEntityViews and takes a filter as an argument. That makes it easy to search for anything. Also I've noticed that searches come back as ManagedObjectReferences and can't be cast to the subclasses. You have to construct them passing the ManagedObjectReference as an argument.
Also I find searching for PowerCLI examples and watching the classes in the immeadiate window very help in navigating this API. It's a fairly decent SDK but they put all of the classes in a single namespace and there's lots of little style inconsistencies ( Device instead of Devices and properties that take strings instead of enums when an enum exists ).

i figured out how to do it :) , by using http://vcenter_hostname/mob I was able to walk through api better. here is what I did, plus instead of of using "host" which was type HostSystem I jused my instance of my vCenter host "client"
VMware.Vim.LicenseManager lic_manager = (VMware.Vim.LicenseManager)client.GetView(client.ServiceContent.LicenseManager, null);
LicenseManagerLicenseInfo[] lic_found = lic_manager.Licenses;
foreach (LicenseManagerLicenseInfo lic in lic_found)
{
string test = lic.Name.ToString();
string test2 = lic.LicenseKey.ToString();
}
