I have a WCF Service hosted at my server and it is being consumed by client from another server.
I did few changes in the code and tried deploying the code after successful build.
Previously the application pool was set to 32 bit as true but the service opens correctly when i make that 32 bit as false.
Currently it is set to 32 bit true and working fine in QA but when i build it and deploy and run the service manually it fails at opening the oracle connection and throws this error "Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed"..
below is the link to the image of what settings i used in visual studio to build the solution.From the many project folder the yellow highlighted one is the startup project which is set to 64bit and all others as any cpu

I am not sure if i am doing anything wrong with the build for which the oracle gives this error while running the service.the application pool should be set to 32 bit

So I wrote service that is constantly checking some folder and if there are files, they are uploaded to Oracle Database.
Everything is working fine when I'm running it in Visual Studio in debug mode. But when I'm doing release and installing actual service and run it, it throws oracle exception when trying to connect:
Could not load file or assembly 'Oracle.DataAccess, Version=4.122.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. An attempt was made to load a program with an incorrect format.
Service is running and working and writing this exception to log file, so this is not direct service problem. I'm installing this service on same machine where I run debugging so Oracle client is installed and working fine. I also tried to install in on another machine but it trows same exception.
My guess is that there is some problems with rights and how service runs but since it's my first windows service I have no idea where exactly problem is and what to look for. It's installing as local service, when debugging it's running as my user (if I'm correct).
Thanks everybody. It was indeed 62/32 version problem. It was 64 bit oracle client installed and debugging was in 64 bit mode but I didn't notice that this setting is completely separate for debugging and release, now changed release to strictly x64 and it's working.
I need to connect to a oracle database on another server so I don't have acces to the database itself.
I created an application in c# with winforms and I was able use this database when I changed some settings in the build options.
Now I am translating the application into a asp.net website and I got this error:
'Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed.'
This is the same error as what I received when I used winforms but then It was possible to fix it in the build options.
Is it possible to fix this error without having acces to the server where the database is stored?
This has nothing to do with the database server version. It's the version of the client components/Oracle driver that you have installed on the web server and whether your web app is running in 32/64 bit mode. You need to make sure they are consistent (ie 32 bit app uses 32 bit driver, 64 bit app use 64 bit driver). Check the Enable 32-bit applications setting in your IIS app pool advanced settings.
I have Developed an Applicatoin in ASP.NET with C# and I have used oracle database.
my prob is when I am running this application from visual studio 2012 it will throw error like
Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64
bit mode with the 32 bit Oracle client components installed.
but when I host this application in my local iis and make application pool enable 32bit is true then it's working fine.
can anyone please guid me how can I run this from visual studio.
If it is just the ODP use the managed driver from Oracle.

I am getting this error when i am trying to install VS project in a 64 bit System. I already download and install AccessDatabaseEngine . There is any other method to do that, i am using MS Access(Office 2007) database to my application. both systems are using x32 system tools **. if i am installing **AccessDatabaseEngine(x64) it is getting an error your system consists of (x32 system tools)
Try to find out your solution from here
For Web
If you have installed the AccessDataEngine and are still getting the Not Registered error
AND
you are running IIS7 on a 64 bit server,
MAKE SURE
you have enabled 32-bit applications for the application pool associated with the website. In IIS, Right click on the application pool. In the properties window, the 2nd option from the top is "Enable 32-Bit Applications". Set it to true.
I have an asp.net web application that uses an unmanaged 32 bit dll that I have successfully running on my development machine, but when I use web deploy to move the code to our test server, I start seeing BadImageFormat exceptions.
I set the target in visual web developer to x86 and both machines are running 64 bit os's (windows 7 and windows server 2008 r2). I'm not sure what other differences there could be causing the problem. Thanks for any help you can provide.
It turns out that there was a flag "Enable 32-bit executables" or something like this in the config files for the webserver that starts out false under iis 7.5
The error message was a total red herring.
