OK...this is driving me fairly nuts. Running W2K SP2, all current drivers, etc etc etc. The problem is, I can't install any program which has an Installshield installation wrapper, which is pretty much everything. I have checked my DCOM configuration after finding an article that said this might cause the problem, but it was correct. I have checked permissions settings for the whole system, again no problem. I fixed (manually, since the Services MMC snapin would hang when I tried doing it through the GUI; locked services DB I think) several Services back to their correct START values thinking this might have wrecked it, but still no go. I've cleared my temp files, etc, but nothing seems to help.
So when I start the install program, for example ar500enu.exe (Acrobat Reader 5.0, US), it pops up and extracts the install files to the %TEMP% folder, then the ar500enu.exe task continues to run, as does Setup.exe. Neither are using any processor time, they just lock up some memory until I end task on both.
Anyone have a killer solution for this? Its been on-going for about 2 months now...
