Error when running vbs via C# application

Question

I want my C# application to run an external vbscript. This Vbs is performing some actions, and needs to retrieve a data from the registry.

The vbscript is launched, but I've got an error : Unable to open registry value for reading.

I don't really understand why.

That's how I run the vbscript :

            Process scriptProc = new Process();
            scriptProc.StartInfo.FileName = @"c:\windows\system32\wscript";
            scriptProc.StartInfo.WorkingDirectory = repository + p + "\\"; <-- location of my script : C:\temp\soft\
            scriptProc.StartInfo.Arguments = "MyScript.vbs";
            scriptProc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
            scriptProc.StartInfo.Verb = "runas";
            scriptProc.Start();
            scriptProc.WaitForExit();
            scriptProc.Close();

And in my VBS, I read the value like that :

strValue = objShell.RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\MyKey\MySubKey\MyReg_Sz_Entry")

Where "MyReg_Sz_Entry" contains a string value. This value is correctly returned when i run the vbs normally, but not with my C# code.

My account has administrative privilege.

I need some help :).

Thank's

I finally found what were wrong...

That's finally simple : the target architecture of my build.

I changed it in Visual Studio options of my project from "any CPU" to "64 bits", and it's OK now.

Thank you very much for your help.
