Print Spooler will not start due to dependency. ERROR_INVALID_IMAGE_HASH577 (0x241) Windows 7

I hope this is a quick one. I have a Windows 7 user that has not been able to start his print spooler in a few weeks. I dug though this event viewer today and found his spooler will not start because of a dependency. HTTP server will not start and I traced it down to;

Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source

Does anyone have a fix? I am hoping it is a registry setting or drive I need to delete somewhere.....thanks

Have you tried uninstalling the current driver then reinstalling the latest driver from the printer's manufacturer's website?  The driver may include that file.

The MS FixIt tool for printers should resolve service dependency issues for the spooler.

See this TechNet blog post for a description of the 2 tools & links to each one.

I would start by running the "Light" Fixit tool.  If that doesn't work, you may need to run the "Full" tool. But, that will reset Windows 7's print environment back to factory settings: so be prepared to re-install printers & drivers if you run the Full version.
