I think actually I forgot to mention something for you.
For this utility to work, you should put in in a folder, which is listed as a path in the Windows environment.
I copied the envtscip.exe from the download into the c:\windows\system32 folder, which by default is included in the pach environment.
That means, it can be called from any folder in the Windows session, and the script will also be able to call it.
I think this is going to finally solve it.
Sorry I forgot to mention it before.
