Can't uninstall WindowBlinds

Have you tried doing the uninstall using the Windows Uninstall and not Wise Uninstall?  If you have and you get the same thing then somehow your Install.log file got deleted and the uninstall cannot proceed without it. After applying the standard Aero theme in Windowblinds, unload it and then try using the Forced Uninstall method with Wise. If that does not work then manually delete all associated Windowblinds (after unloading it) folders from your hard drive and then run a good Registry Cleaner (like Wise, TuneUp Utilities or CCleaner.  Run your registry cleaner until everything comes back as clean, then reboot. Should resolve your issue just fine I would imagine.

You could try the ODNT Zapper to uninstall WindowBlinds.

Note: ODNT Zapper - Utility program that can be used to unload or remove Object Desktop components (like if an install.log file is missing). Warning: this will delete any installed skins/themes for the component when used to uninstall that component.

Thanks LightStar, your advices helped me a lot. I didn't manage to uninstall it normaly but I removed it from my PC with forced uninstall from Wise.

Unfortunately, you still have a registry full of stardock and wb entries. Have to do manual searches to get them all. Registry cleaners will get most probably though. Nothing harmful is in it though!
