Excllink unusable - Class Not Registered Error

4 views (last 30 days)
I am unable to use the spreadsheet link add-in for excel.
I just added exlink addin : C:\Program Files\MATLAB\R2019a\toolbox\exlink\excllink.xlam to excel add-ins.
Whenever I boot excel or try to interract with add-in (e.g. by starting Matlab from the add-in), I get the following Microsoft Visual Basic error:
Run-time error '-2147418113 (8000ffff)':
Class not registered.
Actions already taken :
  • Rebooting my pc and excel : no improvement
  • Checking 'SpreadsheetLink' under Tools/References in Excel Visual Basic window : no immediate improvement, does not stay checked upon rebooting excel
I also found the following 2018 (outdated?) help post, however I cannot find the fm20.dll in either specified folder.
Matlab : R2019a
Spreadsheet Link : Version 3.4.1
Excel : Office 365 / Version 2008 (Build 13127.21506 Click-to-Run)
OS : Windows 10 64-bit

Solved the issue myself.
Running /regserver on R2019a as described in the link below worked for me.
