BUG (Win 7): An error has occurred while reading the Context Menu settings...
Using Windows 7 with UAC on and logged on as an Administrator, setting either of the options to add FileSeek to the context menu for Windows File Explorer completes successfully, and the option appears in the right-click menu.
However, the next time the Settings dialog is brought up, the error message 'An error has occurred while reading the Context Menu settings. Requested registry access is not allowed.' pops up and the settings are cleared.
Assuming you are still logged in as Administrator (and by this I mean the local 'hidden' administrator account, not a user with administrative privileges) and UAC disabled, right?
I haven't had a chance to use FileSeek with Win7 yet, but this is on my "todo" list. I have recently started testing all of my applications with Win7, but with a dozen applications to test I can't fix them all at once. The next release of FileSeek should have better compatibility, but I don't have a release date for it yet.
