ABP 1.1 will not enable under IE32/64 on Win7 Pro

[OklahomaDave]

I have downloaded and installed APB 1.1 on a Windows 7/64 Professional box with IE11. Although the setup reports success, the add-on configuration page in IE reports AdBlock is "disabled", and regardless of the mechanism tried, it will not "enable."

I have uninstalled ABP, rebooted, and reinstalled - twice - same result. I've tried under both IE/64 and IE/32, with no success. Virus scans (Avira) and separate scans from SpyBot each come up clean. No special/unusual tools installed on the box. I've run out of ideas to guess why ABP will not enable.

This Win7/64 Pro install is on a very generic/otherwise unremarkable Dell Inspiron N5110 w/i3/2310 CPU and 4GB of RAM. Have installed APB on Chrome on the same box and it works perfectly.

Have read several forum posts on similar issues and have had no success. Cannot see anything unusual about this IE11 install that would/should prevent ABP from working - absolutely no unusual elements like developer tools or things of that nature that might affect ABP.

I have solved this problem.

The issue was not specific to AdBlock, but to ALL IE11 add-ons for this box.

The problem, which was revealed to me by trusty ol ProcMon, was that some other since-removed malware removed ALL permissions to the ApprovedExtensions registry key for Internet Explorer. I restored these permissions to the relevant user(s), and AdBlock was then enabled successfully and now works just fine.

For others in the same or similar boat, the registry key affected was:

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Approved Extensions

And ALL permissions to the key had been removed.

Had this happen with a system I just cleaned malware from. Editing the registry key worked. Thanks.
