"This program might not have installed properly"

[denzilla]

I un-installed 4.12.2, upgraded the sptd to 1.56 and proceeded to install 4.12.3 and everything worked fine. I restarted my PC about 8 hours later and got greeted with the old "This program might not have installed properly" error message for dtools as the system was shutting down. I was able to click the confirmation that it was installed properly just before it powered off so everything is still ok but why didn't I get prompted with that message right after installation? Under Vista's problems and solutions center, it posted this appcompat.txtr:

Something wrong here?

[denzilla]

One other problem I ran into that may or may not be dtools: The "Previous Versions" feature provided in Vista Business ceased to operate for me recently. When I checked a file's properties, there were no previous versions available. After un-installing sptd and dtools, they all showed up again and everything was normal from that point on.
