Installing Installaware when C: is low in space

[tofutim]

I'm upgrading to Installaware 18, but I'm having problems. I have less than 5 GB in the C:/ drive thanks to VS2013 (it is a fast drive). My temp drive is in D: which has about 800 GB. However, Installaware somehow fills up the rest of my C:/ drive before I even get to choose where it gets installed to D:. Is there anything I can do to set the temp drive for the Installaware installer?

I'm talking not about my own installer, but the actual Installaware 18 installer InstallAware_18_with_Runtimes.exe.

Speaking of which, where are those temp files stored anyway, I only have 44 kb left in C:!

Aha, I just discovered that %TEMP% and %TMP% while pointed to D:\Temp\2 in my account, are pointing to the Admin's AppData in C:! Will try changing that, as IA is installed by the admin after UAC.

The solution above worked - except that I had some custom translations that got wiped out by the upgrade process.

Dear tofutim,

did you use the UNICODE upgrade tool?

All the string resources must be in UNICODE format with IA 18.
