Question

MathCAD - not a valid XML worksheet error

I have been using MathCAD 14 for several years and it does an excellant job for me. I don't make any complex calculations, just simple algebra. I just got a new computer and I installed my MathCAD14 license on it and it works fine. That was much easier than the previous times I had to do that.

Now I have a problem with some of my existing files. I get this error message.

I still have the old computer with MathCAD and I can open these files fine with the old (but same version) of MathCAD 14. I have tried opening them againg and resaving them, moving them from the network to my local computer and also saving them in older MathCAD version i.e 13 12 and 11. Nothing works.

Is there a way around this?

I see my snip does not show in the previous post. The error is "The requested file is not a valid Mathcad XML worksheet."

Yes, you can't simply copy and paste pictures in your post - you are supposed to use the appropriate icon to insert a picture.

Can you provide one of those worksheets? If you click on "Use advanced editor" at the upper right you get the option to attach files at the bottom of your post.

Can you attach this worksheet to the message?

The attached file opens fine using Mathcad on my old computer but refuses on my new computer.

I did find a work around. I open a new worksheet on my new computer and save it as a empty worksheet. I then open that file on my old computer and copy and paste the contents of the bad file into the blank worksheet. I can then open that worksheet on my new computer. I have only tried it on one file so it may not work on all of them.

This opens fine for me, so it's your new installation of Mathcad that's the problem, not the file.

If you go to "help", "about" in Mathcad, do you see the exact same version numbers on both PC's?

What's the OS on the new and old PC?

Latest update:

Thanks for the help but some of those things are beyond me.

Yesterday I had Mathcad crash when I tried to change the units on an existing worksheet. I got an error that it could not find a file. The path given went to the old computer (I shared most of the files across both computers) and then back to the new one. Strange! I don't remember exactly how I installed Mathcad but I wonder if I accidentally used the install file on the old computer?

I decided to reinstall Mathcad. The uninstall process has hung. See the attached snip. Does anyone have a suggestion how to proceed from here?

Computers are great when they work but when things go wrong it gets complicated. Sometimes I wish for DOS days when I would simply erase the file and copy it over. I guess I could go into the registry and try to erase all traces of Mathcad but that seems pretty dangerous. I know just enough to get myself in real trouble! 🙂

Update again. It works.

I had the uninstaller hang, the installer hang, unauthorized user from PTC license site but eventually I got it to work and it opens all the files that I tried so far.

Thanks for all your help.
