Issue Details

I have installed the TDM Excel Add-In from the National Instruments website. However, I am unable to open TDMS files in Office 365™ Excel (desktop version). When I open a file, something flashes but the file does not open.

Solution

  1. Check to see if you have the TDM icons within the Add-ins tab in Excel. The icons look like the following:
 
Note: If you see these icons, use the instructions in the Troubleshooting the Excel Add-In for Microsoft Excel to open TDMS files in Excel.  
  1. If you don't see these icons, check to see if you have the option enable the TDM Excel Add-in using the instructions to enable Add-ins on the Microsoft page.
  2. If this option is not available, re-install the TDM Excel Add-in by running the installer as an administrator (Right-click installer > Run As Administrator) because it is possible that the Add-in may not have installed correctly.
