I had to uninstall SW 2012 and clean the scrub the memory, reboot, and reinstall 2012 and re-download and install SP04, reboot again. I still get an internal error message, but am able to view my drawings.
I ended up uninstalling SW 2011, 2012, and 2013. And reinstalled 2012 Sp 5 and 2013 from my downloads folder. On the bright side, my SW Office upgraded to Professional
I attempted updating my 2012 install to SP5. It gave me a general error message that it was unable to update. I was able to open SW and verify that it was still SP4. Now, I am unable to open or create drawing files, only parts and assemblies.
Anyone have this issue with the update to sp5? I'm away from the office, running SW remotely, will I be able to repair the installation with the DVD?
