Question

Windows 7 Pro x64: Installing Mathcad 15 and Prime 3

I had this all working before I re-installed my OS. Now I can't figure the trick out. M15 doesn't error, but it doesn't run, either.

I've tried installing M15 and MP3 in different orders.

I note that there are two statements about .NET: one says at least .NET 3.5.1, and the other says exactly .NET 3.5.1. I have both installed, it seems, or at least .NET 3.5...

I can find Microsoft .NET Framework 3.5.1 Service Pack 1 references on the web, suggesting that 3.5.1 is a different version, but so far no place to download 3.5.1.

A doc on the PTC website says NET Framework 3.5 SP1, so I guess that I am OK there.

I have tried several suggestions on this forum, to no avail.

I filed a support ticket, but don't know if I'll get an answer, as my maintenance has expired.

Can anyone point me to a definitive solution?

BTW, the note for Tags below has this comment "use >>communities<< to separate multiple tags, use an underscore to combine two words"

Thanks,

Edit 2014-07-08: I found in Control Panel > Programs and Features > Turn Windows Features on and off that Microsoft .NET v3.5.1 is enabled. I am wondering if I must now remove .NET 4.x, and maybe 3.x, and re-install in version order, activating M15 after 3.5 is installed?

It shouldn't matter what order the .NET versions were installed.

I'm interested in the outcome of this, because I'm going to replace my PC soon and have not decided whether to get the 32 bit or the 64 bit version of Win 7. There are obvious reasons why I would prefer the 64 bit version, but some old software will simply not run (or possibly not even install) on the 64 bit version. If it's a problem getting Mathcad running on 64 bit that would certainly force my decision.

Unfortunately, I can't recall whether I had this problem some time ago when I installed Mxx. I now wonder if I gave up and installed M14 instead. Source files (xmcd) indicate M14, not M15. I decided to download a new install of M15 trial from the PTC website, but got trapped in a delightful loop --- click on the link to download M15, go to a page ro down load it, click the link to download it, go back to the page whence you came --- repeat.

This page

sends me here

http://www.ptc.com/WCMS/files/113152/en/mathcad15.pdf

which says

Windows XP Professional x64 SP2

and my desktop says SP1, so I'll see about SP2... though I am current with upgrades, and I thought that meant equivalent to SP2.
