I doubt this post will get many views given that it deals with the now ancient CVF 6.6, but I'll give it a shot anyway...
I have lots of old executables built with CVF 6.6, Pro coupled with Winteracter GUI developer. The code did use the IMSL libraries quite a lot. These live on an old XP machine and run fine. At this point, I no longer do much Fortran programming and certainly have no need for anything fancy. I just need the old code to recompile for an occasional tweak. Yes, I have considered upgrading to Intel many times but frankly I don't have the budget to permit it and really have no need for any new features that aren't in the old 6.6. I'm a one-person operation at the tail-end of my career and it's a stretch to even buy a used computer once every 5-8 years. Plus, I'm aware that a clean migration of the old projects is less likely now that it would have been to an much earlier version of the Intel Fortran. I DID try upgrading sometime back and suffice it to say that things did not go well. I ran into an endless loop of complaints about the wrong Visual Studio, incompatible Microsoft .NET, components that wouldn't install, and on and on. It took multiple trips to the techs to get the computer behaving again and I lost days of work. I can't afford to go through that again.
I hope that this doesn't violate protocol or offend anyone here, but is there anyway to legally purchase the old 6.6 Pro edition? I'm certain that there are lots of folks that still have their disks (I don't) but I don't know what licensing issues are involved should someone be willing to sell it.
I'll duck under the desk now and hope for friendly replies.
