Error opening workbook. If Excel is installed, run the ‘Repair Tool for Microsoft Office Interop’ from the Tools tab on the Home screen

Hi Did we try with WORKBOOK activities Search as workbook in activity panel and try with READ RANGE under that This doesn’t require excel to be installed So it will work in all scenarios Hope this would help you resolve this Cheers @13051156620

[So_Moon]

@So_Moon

1. Please share the excel version
2. If possible try t reinstall office
3. Is the license a valid one or a cracked version?

cheers

2. i dont have the authorizations to reinstall office , it is a work computer, but i use the repair online tool

3. it is valid license

I’m sure the problem comes from office, because i also cant use power point activities, maybe there is a corrupted version but i dont know how to find it
