I don't know if this has been posted before, but:

If you're getting the "Pure Virtual Function Call" error message,the problem may be that you installed with anti-virus softwareenabled, like I recently did.

Do a complete un-install including registry and re-install withanti-virus disabled.

Apparently anti-virus software can intercept .dll files during theinstall and the result is a whole lot of lost hours, believeme.SolidworksGeneral
