I have the same error.
WinXP, Quartus 10.1 Web Edition
First I upgrade from Quartus 7.2 Web Edition to 9.1 Web Edition:
7.2 projects compile correct under 9.1- but much faster!
Then I tried out 10.1 Web Edition:
The same 7.2 project get error during compilation:
Error: Selected feature of TimeQuest Timing Analyzer is not available with your current license, or license does not exist
I checked the license setup:
License File:
C:\altera\72\0050BF911FC6__0-351914914023092.dat (my Web Edition license file for Quartus 7.2!)
I thought that newer Versions of Quartus Web Edition don't need a license?
Maybe this could be the error?
There are no "Classic Timing" assignments in the project...
