Process x86 vs x86_64 issue

Hey guys,

Before I start explaining the issue. I'm working with the 4.6.1 version of Unity since this is mandatory at the company I'm creating this application for. So maybe it's a bug in this version that has been solved later, if that's the case please let me know.

Anyway, I've got a problem with the 'System.Diagnostics.Process' class. Here's the code where the issue is located:

 System.Diagnostics.Process[] pname = Process.GetProcessesByName(applicationName);

Now when I built this in x86_64 settings, it does the job without any problems... It gets the process with the applicationname. So then I built it in x86 mode and I got a nice big fat error:

 InvalidOperationException: Process has exited, so the requested information is not available.
   at System.Diagnostics.Process.get_ProcessName () [0x00000] in <filename unknown>:0
 at (wrapper remoting-invoke-with-check) System.Diagnostics.Process:get_ProcessName ()
 at System.Diagnostics.Process.GetProcessesByName (System.String processName) [0x00000] in <filename unknown>:0 
 at Main.ProcessCheck () [0x00000] in <filename unknown>:0 

To debug I've tried to find and print all processes, but that also gave the same error.

So basically... It works great in x86_64 mode and it crashes in x86 mode... And guess what, the company want the application in x86.

Any ideas on what is causing this issue? Thanks!
