I can't start Mathematica 10.2 in Windows 8.1 64 bit, I'm getting this error even after I uninstalled and re-installed.

enter image description here

I emailed support a couple fo days ago, but I'm yet to hear from them and I need to get to work ASAP, any ideas?

  • $\begingroup$ This same error was reported in question 94541, subsequently deleted. It also was reported on a Russian Mathematica site, where it was put on hold. It seems likely that Wolfram Inc is your only resource. $\endgroup$

  • $\begingroup$ There is a refresh your PC without affecting your files function in windows. That might help. For the future you should seriously consider having some kind of backup, especially for your important, work-related files! $\endgroup$

This error message has occurred before with a corrupted init.m file.

Check your init.m files if you have edited them. Otherwise, the article @JHM linked to you should fix the problem.


In Windows, remove directory C:\Users\%USERNAME%\AppData\Roaming\Mathematica.
