Beware: 7.2 is NOT Vista compatible

JariS, Sorry you had trouble installing Quartus II software on Windows Vista. Our QA team puts significant effort in ensuring a high quality installation and OS support. I appreciate your effort in pointing out that our readme.txt is incorrect (we will update). For clarity, the Nios II EDS does not support Windows Vista yet. The plan is to support Windows Vista in early December when we release v7.2 SP1. Quartus II software does support Windows Vista (32-bit and 64-bit) with the exception of SOPC Builder; also planned for SP1. I have asked our applications/software engineering team to resolve the issues you described in your post with either production support, posting a solution (workaround) or a bug fix – all coming by SP1. If you can submit your issues via mySupport we may be able to provide a fix much sooner.
