Question

How to recover a tif damaged mcdx file

I had an mcdx file which opened with no errors in Mathcad prime. However, after i added 2 tif images to the file, the file won't open

and mathcad prime (windows 7 64bits) gives me this error message "The file type is not supported".

I opened the file in a text editor and renamed all the occurences of "tif" to "png", but this did not fix the problem.

The image files are kept in what appears to be a virtual folder and thus i was not able to change the image files externally to match the png entries in the mcdx file.

How can i recover or fix this file ?

Hello!

You need to contact technical support PTC. Create a new "Case" for your problem here: http://www.ptc.com/appserver/cs/case/case_logger.jsp

P.S. Could you attach a file ".mcdx" with an error?

Edi,


I can open your file in Mathcad Prime 2.0 so I suggest you upgrade to Mathcad Prime 2.0. Unfortunately, it is too time-consuming for a developer to fix the file in Mathcad Prime 1.0.

You can download the trial version of Mathcad Prime 2.0 from http://www.ptc.com/product/mathcad/free-trial/. Mathcad Prime 2.0 does not create corrupted worksheets.

I've also attached a PDF of your worksheet, in case that's helpful.

I hope this helps,

Mona
