Libre Office crashes entering a simple calculation

If I enter a simple calculation like “=11+12+3” or “=SUMME(A1:A3)” into a new (empty) calculation and press >Return< Calc crashes.

I already tried to save the (empty) sheet first, to run the program as Administrator and I retried this after removing the contents of “%APPDATA%\libreoffice\4\cache” resp. “%APPDATA%\libreoffice\4\user” as mentioned in another thread I found about Calc crashes - but the problem still occurs.

I’m using Windows 7 Ultimate 64Bit.

Please help!

Did you notice that you posted to the ask.libreoffice section in German language?

Such a problem persisting the creation of a new user profile is very strange. Next step might be a complete de-installation and a subsequent re-installation.

Just one feeble idea: There are issues concerning OpenGL. Did you already turn off ‘Use OpenGL for all rendering’? (‘LibreOffice’ > ‘View’)

Even more feeble: The hardware of the graphics system can also be used by Calc via OpenCL (‘Formula’ options). Is this option turned off, too?

If you do not get soon a working LibO installation again, you may (temporarily) use LibO extracted from an artchive in the PortableApps format. No installation needed inthis case.
