I use this code to read the installed speech synthesizer:
System.Speech.Synthesis.SpeechSynthesizer oVoice = new System.Speech.Synthesis.SpeechSynthesizer();
But in debugging I see that it generates an error:
oVoice threw an exception of type 'System.PlatformNotSupportedException'
So when I run the next line of code:
var oV = oVoice.GetInstalledVoices();
I'm getting this error:
No entry installed on the system or no entry available with the current security setting.
But I have three voices installed, I checked in the control panel and tried them.
I don't understand why I get these errors.
I use Windows 10 Enterprise, Visual Studio 2010 (I have 2019 but I can't use it now) and Framework 4.0 (and I can't change it).

I have Xamarin installed both on my Visual Studio 2015 and my MacBook Pro with OS X 10.11.4. The problem is that when I try to connect from VS to OS X, it says that for some reason it can't start the Designer agent.
As far as I see from the log the main problem is in this:
Xamarin.VisualStudio.IOS.MacServer Error: 0 : [2016-04-03 21:21:44.1336] An error occured starting the Designer 4.0.3.214 agent: Xamarin.Messaging.Client.AgentConsoleRunner Information: 0 : ==== :: Xamarin :: 4.0.3.214-cycle6-c6sr3+0dd817c ====
Xamarin.Messaging.Client.AgentConsoleRunner Information: 0 : Starting Designer 4.0.3.214...
Failed-Native type size mismatch between Xamarin.Mac.dll and the executing architecture. Xamarin.Mac.dll was built for 32-bit, while the current process is 64-bit.
Is there any way to fix it? Btw, here is the full log http://pastebin.com/iB6X0XWe
I see a number of issues in that log. One that caught my eye is that it failed to download provisioning profiles. Make sure that XCode is installed (and up to date) and that you can run it. You might also need to log in to the Apple dev portal and accept a license agreement - sometimes the portal will block some actions if there is a pending agreement.
Also, it looks like your Xamarin install on OSX might be slightly different (or might be on different channel):
There is a mismatch between the installed Xamarin.iOS (version 9.6.1.9) on the Mac MacBook-Pro-Andrey.local (192.168.0.3) and the local Xamarin.iOS 9.6.1.8. While this may not be an issue, it might cause unexpected behaviors. When applying updates, make sure to keep both the Mac and Windows in sync.
I would fix that first before doing anything else.
I have a problem that an instance of an AggregateException causes a TargetInvocationException after a couple of accesses to an Icon resource.
I broke down the problem to the following steps to reproduce (.Net 4.0 full or client profile):
Create a new WinForms application (a console application will not work)
Add an arbitrary icon (.ico file) to the resources
Add the following code to the constructor:
new AggregateException();
for (var i = 0; ; ++i)
{
var icon = Resources.Certificate;
}
You have to change the resource name to the name of your resource.
That's all. Yes I know that this sample doesn't make sense. It's just to illustrate the problem. My working code is much more complex and all of this code is needed.
Without creating this excection the application will work forewer. But if this exception is created the access to the resource will fail with a TargetInvocationException. The InnerException told me that the operation has been finished successfully(?!?!) having a two-line stack trace in System.Drawing.Icon (ctor + Initialize).
What can I do to prevent this problem?
EDIT
It seems to be a problem using Windows 7. A binary which fails on Win 7 will run correctly in Win 8.1.
I found the reason for that problem:
The following system configuration is needed to reproduce the issue:
Windows 7 German Edition
Microsoft .Net Framework 4.5.2 installed (yes I know my binary is compiled against .Net 4.0)
KB2901983 installed
Having a machine which only contains the .Net Framework without KB2901983 the program works fine. After installing KB2901983 the program fails for the same binary (no recompilation required).
I tried to uninstall KB2901983 but it doesn't help. If it was once installed the program will fail. I tested it on a clean Windows 7 German Edition.
rptdoc.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, true, "DO- " + DateTime.Now.ToString("dd-MM-yyyy HHmmss"));
Above line of code is throwing this exception:
An exception of type 'System.MissingMethodException' occurred in CrystalDecisions.CrystalReports.Engine.dll but was not handled in user code
Additional information: Method not found: 'CrystalDecisions.ReportAppServer.DataDefModel.PropertyBag CrystalDecisions.ReportAppServer.ReportDefModel.ISCRExportOptions.get_ExportOptionsEx()'
I am using Visual Studio 2013 and Crystal Reports 13
Once I faced the same issue on my production server.
until the day before everything was working good, but the next day, the error was showing up.
After long hours struggling with issue i remembered for some testing reasons, i had changed the "Application Pool Settings -> Enable 32-Bit Applications" to True, while my server is 64bit; i changed it back to false and everything got normal.
If your server is 32 make this option True, otherwise make it false.
try to add this in your code:
VB.Net
Imports CrystalDecisions.Shared
Imports CrystalDecisions.CrystalReports.Engine
C#
using CrystalDecisions.Shared;
using CrystalDecisions.CrystalReports.Engine;
and Add a reference to your project for the required dll, or you can install crystal report viewer to your machine
if your windows is x64 make sure you make your application target x64 or any CPU not X86
and the same if you use windows 32 bit make sure that you set project to target x86
I'm getting the below error when I try to run the app certification test on my windows 8.1 app. I've looked around for a while and can't seem to find any solutions for this. The app is written in C#/xaml which I wasn't aware even had a linker.
I'm hoping that someone can guide me in the right direction on how I should start to investigate an error like this as web searches have thus far failed me
Binary analyzer
•Error Found: The binary analyzer test detected the following errors:
◦File [MyTabletApplication.exe] has failed the AppContainerCheck check.
•Impact if not fixed: If the app doesn’t use the available Windows protections, it can increase the vulnerability of the customer's computer to malware.
•How to fix: Apply the required linker options - SAFESEH, DYNAMICBASE, NXCOMPAT, and APPCONTAINER - when you link the app. See links below for more information:
If you are using Visual Studio 2015 and this is a new solution/project make sure the 'Compile with .NET Native tool chain' check box is cleared in the startup project properties in the Release configuration.
My app runs fine on my machine (of course/famous last words). However, when deploying it to another machine on the network, it won't even start up. I ran my EventLog utility on that machine and it told me this:
Type:Error

Message: Application: duckbilledPlatypus.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.TypeInitialization
Exception
Stack:
at duckbilledPlatypus.PlatypusMainForm..ctor()
at duckbilledPlatypus.Program.Main()
So it's something in my main form's constructor that's the problem, apparently...which, I admit, is a little "busy":
InitializeComponent();
foreach (string arg in Environment.GetCommandLineArgs())
{
if (arg == "-DEBUG")
{
InDebugMode = true;
break;
}
}
SuspendLayout();
tsch = new ToolStripControlHost(dateTimePickerScheduleDate);
toolStripPlatypusMain.Items.Add(tsch);
CreateTableLayoutPanelAndChildren();
LimitPlatypusIDTextBoxesToOneChar();
ShareEventsAmongDynamicTextBoxes();
SetAllPlatypusDataControlsReadOnly();
ResumeLayout();
Does any of this look problematic? (it's all pretty standard stuff, except for the ToolStripControlHost).
Now as to the framework version: does the Event Log report the framework version used to create my app, or the framework version installed on the machine trying to run the app? If the former, and the latter does not have that framework installed, that's a problem, right?
So if that's potentially the problem, how do I determine which version of the .NET runtime is installed on that machine?
UPDATE
I don't know why this is, but I was able to see an err msg after running the app on the remote/deployment only when I right-click and select Run As (and ran as myself, as I don't have any "more special" privileges on that machine). When I did so, I got "Unable to find a version of the runtime to run this application."
If I simply 2-click the app, it dies without a whimper (no err msg).
View the
view the %WINDIR%\Microsoft.NET\Framework directory
to determine which versions of .NET are installed.

Try running the Fusion Log Viewer on the problematic machine. It will provide details about binding failures.
http://msdn.microsoft.com/en-us/library/e74a18c4(v=vs.100).aspx
Make sure you run it as administrator. It silently fails if you do not.
UPDATE
Based on your error "Unable to find a version of the runtime to run this application.", I would suggest you don't have the same version of .NET installed on the box that your application targets. Did you verify the installed versions using the steps above?
