Multiple Quartus versions installed 6.0 to 12.1 SP1, Win 7 IP Megastore used to work. Now nothing in any version. - did installation of newer Quartus versions make this stop working? or - because my subscription licence is now past expired?

Hi,

- did installation of newer Quartus versions make this stop working?

>>No, We are using multiple Quartus installed in systems. However sometimes files may be corrupted, try by reinstalling the Quartus.

- because my subscription licence is now past expired?

>>Without license, We can create a projects using Quartus tools without Analysis & Synthesis.

So license may not be an issue.

Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

Regards

Anand
