Run multithreaded function using while?

[Tripredacus]

I have a problem where I am trying to install a program on Windows 7 Pro x64. This program will fail to install if the process mscorsvw.exe is running. My script is designed to install the program and reboot the computer. In a 64bit environment, there are two of these processes, mscorsvw.exe and mscorsvw.exe *32. I run 2 ProcessClose() commands which DO get these processes to disappear, but there is a problem. First, my code:

If FileExists ( "c:\temp\app\install.cmd") Then
    ProcessClose("msiexec.exe")
    ProcessClose("mscorsvw.exe")
    ProcessClose("mscorsvw.exe")
    sleep(1000)
    RunWait (@ComSpec & " /c c:\temp\app\install.cmd")
EndIf

The problem is that the beginning of the CMD is processed (I cannot post the contents of the CMD file) but before the CMD is processed, mscorsvw.exe starts itself up again.

Is there a way to keep this CMD running AND stop this process from opening until after it is done?

PS: What is interesting is that this code (without the ProcessClose statements) works fine on Windows 7 Pro x86. FYI, the mscorsvw.exe processes were started by the installation of another program. I require both of these programs to be installed one after another.

mscorsvw.exe (Microsoft Common Language Runtime Service Host)

Just stop the service. When you reboot, it will startup again.
