Windows 7 Home Premium N x64.
Unrestricted Admin account, UAC off.
Tried with ESET Smart Security off, but results were the same.
My initial problem involved not being able to install Impulse due to errors about not having admin rights. I sent in logs [#QME-952273] but they didn't help at all.
As per my conversations with support [#ZQY-681319], I tried CleanImpulse.exe, I tried sfc /scannow, I tried running a repair install of Windows. I even ran Impulse in Windows XP running in Virtual Box and it installed fine, further indicating a problem specific to my machine.
Support finally stopped responding. In desperation, I reinstalled Windows, and as soon as the new, clean OS was up and running, I managed to install Impulse and then WindowBlinds without issue.
That was several months ago. WB has been running fine. I realized yesterday that it wasn't auto-updating, so I opened Impulse. Impulse tried to update, but ran into the same errors about admin rights, and now won't let me update any of my other Stardock apps.
This all suggests to me that something I have changed or installed since reinstalling Windows has blocked Impulse again. As I look through my list of installed apps, nothing jumps out as particularly intrusive. I do have my uxtheme.dll and related files patched to run unsigned themes, but I can't imagine that's the problem, is it?
