If you have experiencing a problem with Ms. Excel 2010
“Object library invalid or contains references to object definitions that could not be found”
like picture below :
Maybe this solution can solved the problem :
Unregister and then register back the mscomctl.ocx.
Please copy below script into notepad and then save into mscomctl.bat
regsvr32 /u mscomctl.ocx
After copy that script, run mscomctl.ocx using administrator privilege.
I hope this solution will help you, if you’re found same problem.😀
