Issue Details

I installed TDM Excel Add-In for Microsoft Excel but when I open my TDMS file on excel I can see special characters : 
How to fix this issue ?

Solution

You can try several things:  
  • Check in Options, whether Excel 'sees' the Add-in. Open Excel and go to File -> Options -> Add-ins
If Excel doesn't see it you can browse manually the add-in. Click the Go... button (bottom of the window) and find ExcelTDM.dll file.
 
 
  • Try to open the file with another Windows session on the same computer ​​​​​​. If you can open the file, your session is probably corrupted, ask to your IT Service for a solution.
