Somehow I got into a borked state where I cannot uninstall the current version I have. The crux of the issue is that I lost "unins000.exe", it just doesn't exist on my computer any more :-(
Two key things I've tried:
Going to programs and features out of control panel, and then uninstalling from there fails because the above EXE is missing.
The attached picture is what happens when I run the new installer I just downloaded. It fails with a misleading error of "access denied".
Any ideas on how to uninstall? I much prefer doing things more cleanly than simply remove the "program files/Heidisql" directory and mucking with the registry by hand. I prefer to keep my settings intact, in particular connection information and passwords, as I have quite a few.
