You've been busy!
I have 32-bit and 64-bit versions, but I have never run a command line, so I'll need to check this out.
To avoid uninstalling until it's safe to do so, could I rename the TTS-1 source folders after I have copied?
I appreciate your help but it's 1.30 a.m. here, so I'll check it out tomorrow.

Thanks again,
Vintage
