"failed to launch server application" error in Quicksheet

[thall]

Using Mathcad 14 (MO20) under Windows Vista, 32-bit.

Help / Quicksheets / Engineering Applications / WAV files, Spectograms, and Signal Generation.

This Quicksheet repeated fails with the message "failed to launch server application" awhen I try to scroll past the last line

in the attached image. Occasionally Mathcad hangs and has to be shut down with the Windows Task Manager.

The embedded WAV file loads fine, as does a WAV file read in from disk.

Why would a pre-tested Quicksheet be giving such an error? Any idea what could be going on?

Thanks,

Tracy

I tested in Mathcad 15 M030 version and it works fine. I recommend that you upgrade to the latest service release for MC14 - M035.

Do not install M035. It has a serious bug. M030 is the last usable release for MC14.

Richard,

?? There is only one M030 for MC14.

I mean bug.

[RichardJ]

Do you mean which bug? Actually, it's long enough ago that I don't recall, I just recall that M035 has a bad bug.

It was a bad memory bug. Every time after closing the program it still remained in memory and the process had to be killed via task manager.

Now and then this still happens with the current M030, too, but fortunately not too often.

Yes, I remember now. Thanks for jogging my memory.

[VladimirN]

Thank you, Werner.

[VladimirN]

Yes, bug.

I think the 3D plot component is not registered correctly. Try repairing the Mathcad installation.

Thanks to everyone for the suggestions. I tried to repair Mathcad in the Windows Control Panel, but I got about 16 messages warning that various objects had failed to register. So I completely uninstalled MathCad, the Resource Center, and HelpCenter. The uninstall left about a hundred orphaned objects in the registry, which I discovered and cleaned with Glary Utilities. Did a new installation, and everything works fine.

As a tip for the future, in the Mathcad program folder you will find "regtool.exe". Running it will register everything that Mathcad needs to function.
