Re-Installation Problems

All of a sudden when I started trying to run MC14 (Windows XP) I started getting the error message

Microsoft Visual C++ Runtime Library

Runtime Error!

etc.

The application has requested the Runtime to terminate in an unusual way.

I followed the suggestion in an earlier post to install the prereqs before re-installing MC14. I do not get the error message any more, but now the MC14 doesnt start.

Help?

The later service release of 14 requires a later version of dotnet (3.5 in fact). Download and install dotnet 3.5:

This may require you to uninstall earlier versions, but don't worry about that. The installer will also install versions 3.0 and 2.0. Once they are installed you will need to use Windows Update to install a number of service packs. Keep cycling through Windows update until there are no more essential updates.

As an aside, it's not a good idea to remove prerequisites like dotnet versions from your computer unless you are 100% sure you know exactly which software packages rely on them (which, since a software package may not advertise it's reliance on a particular prerequisite, is almost impossible).

Your post implies that Mathcad used to run OK on the same machine. Have you tried repairing the Mathcad installation?

Yes, it did run fine until I cleaned up some files to clear disk space (and obviously screwed something up). I did try to repair MC which did not work. Then tried re-installing the prereqs (I had trouble re-installing Net Framework on the MC as it required deleting some later versions). Now repair says it is fine. But when I start the program, the logo comes up, but then nothing happens. It is, however, apparently running because if I shutdown the computer, it asks if I want to end the non-responsive program MC.

Thanks for the response. Maybe the more info above will spark some ideas?

You could try uninstalling Mathcad completely and reinstalling.

But, you say you had problems reinstalling the dotnet framework? What do you mean it required deleting later versions? Which version of dotnet were you trying to install? If you go to add/remove programs, which versions of dotnet do you have installed?
