With these steps, you can avoid many common problems in your use of Mathcad. If you encounter any errors after taking these steps, please contact Technical Support with the details and sample Mathcad files, so that they may investigate the problem further.
Return to the Table of Contents
You can install and run Mathcad alongside Mathcad 11 and/or any later version, to ease conversion from old worksheets to new. The versions must be installed in order, from oldest to newest; failure to do so may cause problems using components. You can copy and paste regions from an older version into a newer version (for example, from Mathcad 11 into Mathcad 14), however pasting from a newer version to an older version is not supported and may crash the older product. When multiple versions of Mathcad are installed, the automation interface will only work on the most-recently used version of Mathcad. This may cause controls that invoke automation to stop working in older versions of Mathcad.

| 060925-131442 | Compare Worksheets allows you to specify unsupported files. |
| 060914-134158 | Plots cannot be embedded in text regions, instead returning the error "The contents of this file have been corrupted." Note: Previous versions of Mathcad inadvertently allowed this. Workaround: To save the file, move the plot outside of the text region. |
| 060912-213659 | Symbolic Laplace transforms return an error in the German version of Mathcad. Workaround: Specify a different independent variable, such as t1, for the transformed function, as follows: f(s) -> Laplace, s, t1. |
| 060901-121829 | The single-line construct of a definition, followed by a symbolic evaluation, followed by a numeric evaluation is not supported, although you can type it in. |
| 060807-130950 | Zero-width joiner/non-joiner Unicode characters do not work in math regions. |
| 060801-113111 | An undefined variable defined in terms of 1*itself (for example: a:=1 * a) numerically evaluates to 0, rather than return an error. |
| 060727-120201 |
[Ctrl] [Shift] K inserts special operators into math regions, but no longer inserts Greek characters. Workaround: Use [Ctrl] G to enter Greek characters. |
| 060630-094017 | The symbolic keyword parfrac fails to return the proper result when:

| 060406-101521 | Cannot use a hyperlink to navigate to a region in an area if the area is collapsed when the file is opened. |
| 060316-153817 | Redefinition Warning tips don't appear until the second time you click on a region. |
| 060307-123707 | The dialog warning you that a file is being opened read-only sometimes fails to appear in front of other windows. |
| 060217-123210 | Multiplication that formerly returned zero now returns an error. Mathcad 2000 and later evaluate all terms, rather than return zero if the first term evaluates to zero, which may cause errors when none appeared before. Workaround: If you know that one term reaches zero, define the function accordingly, using the 'if' programming operator. |
| 060130-104032 | Error highlighting, error messages and Trace Error may be confusing in solve blocks. Workaround: You may be able to trace the real error if you:
|
| 051221-164409 | The MATLAB component no longer supports the display of MATLAB plots, due to changes in MATLAB's Automation interface. |
