I was at a client site yesterday and one PC had a myriad of issues.  After running a couple of av programs, I remved all but 1 issue.  After booting into the OS and onth the desktop, the following error pops up:

Error loading c:\windows\syswow64\actmic.dll
A Dynamic Link Library (dll) Initialization Routine failed

I have been all over the web looking for the fix.  I can't find any info on actmic.dll.  I know syswow64 is a legit folder, but the .dll doesn't appear to be real.  I checked a Vista box I have, and no .dll with that name.

OS is Vista Home Premium x32

syswow64 exists on 32 bit windows?  That sounds strange, but maybe it does exist by default.  Unfortunately my 32b Vista box is completely infected at the moment, so I can't check that one.  Have you checked msconfig to see if you can suspicious apps, or processes that are launching on startup?

I shut everything off in the start-up area in msconfig and checked all services (hid MS services).  Nothing there looked suspicious.  Hope you get your PC running safely again soon.

Have you searched through the registry for the file name? There may be more clues there.

Given the circumstances, it seems probable that it's bogus file. I think it's going to be a matter of tracking down where it's being called from (probably the registry) and nuking the reference there.

Ok.  That makes sense.  I'll be trying to remote the client today and I'll let you all know.

It was a bad file and when finally located in the registry and removed, the issue went away.

Thanks for the help.
