i did a search in the forums, and couldnt find anything reporting this.
if it has or if im doing something wrong then i apologise.

i came back to get a new version of sandboxie (i was using 2.64) and started using 2.80 and then 2.84.
well, it has become clear to me that if im using 2.64, i can "run sandboxed" "windows installer service".
if i try this on version 2.80 or 2.84, it fails, so basicly anything whose instalation is dependent on the windows service cannot be installed.
(NOTE. im using XP SP2 32 bit)

so i go back to 2.64 and there it is, back again, working correctly...

and the reports of bug fixes on new versions is SO vague that i have no idea if 2.85 fixes this or when a new version shows up, if it does.
