Probably not (this is a fairly common problem). When it first starts Fritzing without saying or indicating anything accesses github to update the parts library and appears to hang. If you wait for it usually it will eventually complete and run. It has been said that pre installing git makes this much faster. Although I’ve never (on Win7 pro) had to wait for more than a couple of minutes longer times have been reported. If it is now crashing when you try and start it (or reporting that it is missing dlls which is another common problem) then you may need to clear the user directories to fix that (post and/or check the forums for the instructions as this has come up recently). Good luck!
