I'm having the same problem with Quartus II 32-bit Version 11.1 Build 259 01/25/2012 SJ Webn Edition (SP2 installed), on Win7. Fresh install of everything. Took SOOOOOO long to download, I really don't want to try again with older software. Please try to fix this or find a direct workaround. Thanks.
EDIT: OOPS, didn't see multiple pages for this post, so I didn't get to the end where there's a patch solution. Trying it now...
EDIT: DARN. This won't fix my problem. The fix is for 64-bit version only. Not that I chose it explicitly, but I have 32-bit version running. This problem DOES exist with 32-bit version. So now what do I do????????????
