Hello I have been trying to open Mathcad 7 files on the trial version of mathcad 15 and everytime I get the message "Mathcad Application has stopped working". They are crucial files needed for my research so I would appreciate any suggestion on what to do.

I have also tried converting to XMCD to view using Mathcad Prime 3.1 but always gives the message "Unexpected error encountered during conversion"

Luc!

Try please open in Mathcad 11!

It is imposable in 15 or convert into Prime!

I can confirm that I get the very same error when i try to open those files in Mathcad 15.

On the other hand - Mathcad 15 is capable to open even older files way back to version 2.0 (or even 1.0 ?). So it sure should be able to read files from version 7.

Normally my best guess would be that the file got somehow corrupted, but this would have happened to your whole archive which is not very likely, I think.

So lets wait if Luc, Richard or somebody else with a working version 11 is able to open your files.

Unfortunately, I no longer have easy access to MC11. I do have access, but only by firing up an old PC, which I will not be able to do until this evening.

I can confirm that these are Mathcad 7 files (they start with ".MCAD 306000000").

Mathcad 11 cannot open these files, the error message is: "Failed to open document.", fortunately without crashing the application. They are probably corrupt.

They are binary files, very little is readable. I do not know the file format, so have little hope these can be recovered.

Should I find a way, I'll get back.

Success!

Can't open in mc11, mathcad 6 plus nor Study Works. I haven't mcad 7. My version of mcad 7 was from Mark's Mechanical handbook, and it is not a complete version. But for some reason I delete it.

Best regards.

Alvaro.

Opening in a version below 7 is not to be expected, since they are version 7 files.

You can get the uncorrupted files here: Index of /~tony/watts/watts/teaching/mathcad

Guess you've found the original file set.

The 2.1.mcd files differ as of byte location 16384. That's a power of 2, interesting.

The full list is:

2.1    16384=4000h

3.1    16384=4000h

4.1    20480=5000h

5.1    16385=4001h

5.2    12288=3000h

5.3    12288=3000h

5.4    28672=7000h

6.1    16384=4000h

6.2    16384=4000h

7.1     99    =0063h

7.2    20480=5000h

7.3    36864=9000h

7.4    16384=4000h

7.5    12288=3000h

Now files 5.1 and 7.1 are even more interesting. File system problem?
