I think I found a new bug. How do I report the bug?
Please check that the bug hasn’t been described here before you submit an issue. Bugs are reported as an issue on WordMats GitHub site
Before you submit an issue read how to here: Contributing

The installer says Word is not installed or The WordMat ribbon doesn’t appear.
Check the point above about Office versions.

Error: – compile error …
Try reinstalling. Probably a problem with your Word-installation. Could require a complete reinstall of Office.
On a Mac this error is probably caused by Word 2016 not being updated.

WordMat locks or reports an error.

  • Try to deactivate antivirus. Also try to reinstall with antivirus deactivated. Some times Antivirus software must be completely uninstalled. ZoneAlarm can cause this Error. ZoneAlarm must be completely removed.
  • WordMat will not work if the document is on a network drive.This error can be periodic. On a mac using Parallels ”shared folders” must be deactivated. In Word the default drive could be set to a network drive. Check in Word / Settings / Save

WordMat suddenly disappeared from the Ribbon in Word.
Word has deactivated WordMat. You can reactivate it in startmenu / all programs / WordMat / Reactivate WordMat. You can manually activate WordMat from within Word: Files / Settings / Addons / Choose ’Word-Addons’ .Make sure there is a checkmark by WordMat.dotm. Press OK. Another approach: Files / Settings / Addons / Choose ’deactivated elements’. Mark and activate WordMat.dotm.

Error: Can’t create ActiveX component
Reinstall WordMat with antivirus deactivated. Could also be caused by .Net permission problems on your computer.

My Antivirus says WordMat is a trojan horse
Some AntiVirus programs will report a false positive. AVG antivirus has done this in the past for WordMat.

Suddenly WordMat will not calculate anything. It just worked
Try restarting Word. Also under setting advanced you can restart maxima. You might also have an error in a definition in your document, check a clean document. If the error persist it might be a bad setting which is causing the problem like output-units set incorrectly.

WordMat Excel sheet not working as expected
If you save one of the Excel sheets you have to make sure it is saved as an Excel sheet with macros (You will be warned if you try to save it as a regular Excel document, but can easily be overlooked). If you save the Excel sheet as a regular Excel document a lot of the active parts are deleted.

Problems with embedded Excel files
The error ”Serverprogram, source file or object …” appears when double clicking the embedded Excel sheet. The error can be caused by another addon to Excel like Google Cloud Connect. Deactivate the addon in Excel.

I’m asked to activate macros
WordMat will normally not request this. Maybe you have an atypical installation. You can circumvent the problem by lowering the security level, though this is not recommended. Set a checkmark in Excel: Files / Settings / security center / Settings for security center / Settings for macros / Activate all macros.

Equations are not shown correctly in pdf
Try a different program like pdf-creator.

Word will not open the document
Word Files can under certain circumstances be corrupted. Word can try to repair the file. When you open the document from within Word, you can select ‘Open and Repair’ on the bottom. LibreOffice is strangely better at reading the faulty Word files, and if you are using version 4+, it supports the Word equation format. Always make backups in several versions, in several places.

Word locks completely when pressing backspace in an equation
This is a bug in Word. For Word 2016 it has been resolved sinde build 7070.

Word is sluggish
If you have many equations in the document or a slow computer, it can affect speed. There are 3 things you can do
– Remember to insert ”delete definitions” commands in the document. This limits the portion to be searched through to find definitions.
– The speed can be significantly improved if you change to draft view. Find the tab “View” and under document views select Draft. There is also a shortcut to the bottom right of the screen. Under Settings / Advanced can make it possible to start up in draft view
– You can also turn off the display of images from It. It will also make Word faster. Tables also make the document slower to edit.

Compile error on Mac
This is probably because Word isn’t updated to the newest version. Just check for a new update in the menu. Some Mac-computers doesn’t register correctly that a new version has arrived, probably because of an earlier issue with Microsoft Autoupdate. You can manually install the most recent version of Microst AutoUpdate (MAU) here: Update history for Office for Mac
