[SOLVED] MMC Windows Wallet Will Not Install

[beardedpants]

Well, I fixed it myself.

Running this fixes it for anyone else who may have the same problem:

...or for that matter, won't uninstall either.

I'm attempting to upgrade an old and extremely buggy version of the windows MMC wallet. However, during install I always receive this error message, no matter what I've tried:

I've tried uninstalling the old version first and receive that same error.

Is there a known fix for this?

Thanks.
