Hello @Parker56

 

Welcome to the HP Support forum. Thank you for posting.

 

This seems related to your Microsoft Office application. Please, check the official article from Microsoft about such problems and follow the steps >> https://support.office.com/en-us/article/Error-The-application-can-t-start-because-AppVIsvSubsystems...

Try with Online Repair or complete reinstallation.

 

 

If you continue facing difficulties with this, reach to Microsoft Support >> https://support.microsoft.com/en-us/contact/virtual-agent/?flowId=smc-contactus&referrer=www.google....

 

 

Hope this helps. Let me know how it goes.
