Check for those two dlls in your Fritzing install directory, in my case (Win7 pro) that is
and in there along with
Fritzing.exe (which you obviously have)
If they aren't there check your unzip program (I used the open source 7zip program) and then your virus
checker in case it has decided these programs are a "virus" and blocked them. If they are missing you might try disabling your virus program while you install Fritzing and see if that helps.
