model sim 11.1 wont install, cannot find quartus installation ??

Thank you for the flood of silence.

Turns out that I needed to burn up more of my internet download limit to grab the original ModelSim-Starter 11.1, which was quite happy to recognize the 11.1 sp2 install of Quartus II.

So to recap, where the 11.1 sp2 installer for ModelSim-Starter refuses to recognize an installed Quartus II 11.1 sp2 installation (its companion), the superseded 11.1 version of Model-Sim-Starter will install despite the later service pack of Quartus II being installed.

That would count somewhat as a bug in the SP2 installer I suspect.

Moreover, the original installer does not appear to care to look for an installed Quartus 11.1, it creates its own target directory oblivious, it appears, to the 11.1 sp2 directory I have sitting on my drive.

This actually may not mean much more than the installer for 11.1 sp2 is actually looking for an "11.1" directory as opposed to my install directory called (mysteriously) "11.1 sp2".

So, with two different behaviors between two installers of service packs of the same revision of the software I expect this will catch anyone out.

Stay tuned as I try to discover how to get ModelSim 11.1 sp2 on my machine.
