Unable to cast COM object of type \’System_ComObject\’ error in ALM when attempting to login

Question ID: 109310

Hello,

I am experiencing the following error \”Unable to cast COM object of type \’System_ComObject\’ to interface type \’Microsoft OfficeUcUCOfficeintegration. This operation failed because the QueryInterface call on the COM component for the interface with ID\”. that is being displayed upon an initial log in attempt.  We recently upgraded from Almost 12,53 to ALM 15.00 and I am not sure if this is related.  I have a Windows 10 desktop as well.

Any help with this issue is greatly appreciated.

 

Thanks,

HomerJ

Hi HomerJ,

I have seen this before in other versions as well. This resolution has resolved the past issues relating to this error:

Sounds like there was something uninstalled or missing in your Microsoft Office suite installation that was being referenced during the ALM log in call. You should try repairing the Microsoft Office suite installation. You may have to uninstall or reinstall the entire Microsoft Office suite to get the issue corrected but generally the repair tool resolves this issue. See this article for repairing the Microsoft Office suite installation (you may have to get your IT department involved if you don't have the permissions and rights necessary to perform this operation): https://support.office.com/en-us/article/repair-an-office-application-7821d4b6-7c1d-4205-aa0e-a6b40c5bb88b

Let me know if this helps.

Dan
