What I do with any program is to see and check if it tries to communicate with errorLevel's, always.
Whereas errorLevel zero means there is no error, or the developer didn't care to bother, or it is intended to behave like that.

squashman i was able to run those nice application you told me about and i got a lot modules running, well i did have the list and copied them to a folder in my memory stick; but checking them against the new system it also contains those modules, though some are different in versions, so what shall i do now?

@ed dyreen

it gave me errorlevel zero and as you say i suspect that it was designed that way

have you tried adding a pause in your batch file to stop and check what
the error message is?

it only shows 'press any key to continue...'
