change location where MSI files are cached?

[dstoeberl]

Hello all,

A client wants to be able to install an MSI application with absolutely no overhead required in terms of disk space on the C drive. The application is being installed from the D drive, to the D drive, and the installer (self-extract executable and VBScript) never touches the C drive.

However, the MSI file (~90MB) gets cached in:

C:\Documents and Settings\<user name>\Local Settings\Temp -and-

C:\Windows\Installer

And possibly creates other temp files in other locations (not sure).

My question is, does anyone know how to either force an MSI file to not be cached, or to change the location where it does get cached?

Thanks in advance!
