As for your question, is there any reason you're attempting to use environment variables rather than opening the file directly?  Additionally, one should always be careful when using single-digit unit numbers; many of these units have reserved definitions.

Thanks

I encounter continual stoppages in the install process because of insufficient access rights to a folder called config.msi.
The config.msi folder, in the c:\ root directory, seems to be a hidden system folder.
I have been able to get past the stoppages every time by using the utility program, 'TakeOwnership' on config.msi.
But it is a real nuisance.  I sometimes have to do this maybe ten or more times during a single install or uninstall procedure.

I notice that, when the install or uninstall process has finished, the folder called called config.msi disappears.
Apparently, therefore, it is a temporary folder.  I wonder, therefore, whether it would be possible to place the temporary files created during this process, not in a folder in the C:\root directory, which is a place about which Win Doze systems trend to be a bit touchy, but to put them somewhere else.  Perhaps in a 'TEMP' folder in the program directory.
