How to Install Mathcad 15 on Windows 10

[SSLA]

I installed Mathcad 15 m1010 in Windows 7 and later upgraded to Windows 10 and it ran fine under Windows 10 for a year or so. Unrelated to Mathcad, Windows 10 recently developed explorer issues, faulting every few minutes and restarting. Tried everything finally solving the issue by clean installing Windows 10 and all my apps, except for MathCad 15.

Extract the installer near the root of a disk drive. It will fail if the path to setup.exe is too long.

The Mathcad 15 installer starts and requires that you to down .Net Framework 3.5 at the link provided by the installer. This works. After installation make sure the that all features of version is fully enabled in the Control Panel, Turn Windows features On and Off.

But then load will not run after extraction, gives an error message 0xc000012f that the installer file setup.exe is either not designed to run on Windows or is corrupt. Close it. Right click on setup.exe, select Trouble Shoot Compatibility, Trouble Shoot This Program, check the box "The program worked in earlier versions of Windows but won't install now" then select "Windows Vista (Service Pack 2). You will get some error messages, click through them and Mathcad 15 will install. Show it where your license file is located and it will run as it did in Windows 7.

Got the compatibility tip from:

Good luck!

Forgot to mention: I have owned a fully licensed node locked version of MC15 for several years. I was able to re-install MC15 after a clean reinstall of Windows 10 even though I am not on PTC support. This worked because I was installing MC15 on the same computer that it was on before. If I had moved MC15 to another computer I would have had to go back onto support (half the cost of a new purchase) so that I could self-serve myself a new license key file because the node lock reads the MAC address of the network adapter built into the mother board. Seems like an unnecessary expense for a company in its final year. I plan to retire in December and will no longer need MC15 for professional work.

IF you have sufficient documentation on your original purchase, you can create an account at PTC and can get a license reissued (usually), at no cost, other than time
