Access violation message when opening simulation report

I got the same error. Qsim only runs on V 10.1 or V11.0. Hopefully you still have one of those versions installed.

Thanks for the reply. Yes I remember that Qsim used to work under v11.0. The problem is that in v11.0 there is a silly bug when you try to create a symbol from a schematic file it refuses and displays an error. The workaround was to convert this schematic to HDL then create the symbol from that HDL.

Great, good to hear that you got it worked out. The word I hear is that Altera will be putting waveform editing (vwf) and simulation back into Quartus in the future.

Quartus II 32-bit Version 11.1 Build 216 11/23/2011 SJ Web Edition
Service Pack Installed:  1

I think it may still have something to do with running version 11.1 I had to run version 11.0 to get it to work

Ok, I was hoping it had already been fixed. Where do I go on the Altera site to download 11.0? Most of the links I had were for 11.1sp1 only. I'm TAing a class starting after the new year and I'd like to make it as easy as possible for them, so if there's a easy link to the 11.0 download, that'd really help.

yes version 11.0 is still available at the altera website under SUPPORT DOWNLOADS WEBEDITION FREE. Be sure to uninstall 11.1 and delete the subdirectory that was created for 11.1 first before installing QSIM.
