I was trying to uninstall a bunch of useless programs, and I must have gotten rid of something important because suddenly when I try to open firefox and vlc (and prob other things among that...) I get the following message:

"This application has failed to start because C:\WINDOWS\system32\wxvault.dll" was not found. Re-installing the application may fix this problem."

UGH I'm an idiot. What do I do now?
