Uninstalling
Use great care
It's no secret: I've been having problems with Impulse lately. First, let me say thanks to all who tried to help because you all did what friends do.
The reason may be having used Revo uninstaller. What I'm saying reflects my experience, and I don't want to generalize it, only to spread what I've learned in order to help. Don't get me wrong, please. The Revo Uninstaller (like everything else) should be used with care!
Turns out that it doesn't play nicely with Impulse, especially if you're doing a thorough (Revo level 4) uninstall of an SD program.
That's not anyone's fault. Let me make that clear. This is just what I've found out. Take it for what it's worth. When I try to help folks in the future I'm going to recommend using only the SD ODNT zapper.
It turns out that unless you're planning to uninstall every SD app, it (Revo Uninstaller) shouldn't be used as it tends to track apps back into Impulse and uninstall parts of Impulse it shouldn't.
Probably the best utility to use is the Stardock "zapper", but I'm going to be asking SD support about CCleaner also. When I learn what SD Support recommends, I'll keep you posted.
