I have no issues so far. Which version of Office and Studio are you using?

I have suffered this issue for years. 

I have suffered this issue for years. 

Strange. This happens here maybe once in 3 months... Have you installed Studio as admin? In which order the programs have been installed? Are all the programs completely updated? And does the spellchecking work in Word without any problems?

Thanks!

I installed Studio normally, not specially as Admin. Maybe I should run it as Admin. Office was installed first, and is updated regularly under an Office 365 license. All programs are completely updated. Spellchecking works perfectly fine in Word.

The type of error sounds like some fail in loading the service provided by MS Office. I am not sure what kind of fail, but I fairly understand software issues.

I hope the programmers look into this matter more closely. I have experienced it for years, using all the updated versions of both Office and Studio. And I believe other users are experiencing this same issue. I see comments in this community from time to time.

So try to install Studio again without uninstalling, it will run a repair installation, but this time as admin. Simply right click the installer file and select "run as admin". Could help.

Thanks!
