SharePoint 2010 Error: Failed to call GetTypes on assembly Microsoft.Office.InfoPath.Server

I had installed Microsoft Office 2013 on top of SharePoint 2010 standalone version. I was trying to create a new web application and the operation failed all the time giving 404 errors and the ULS logs had errors as below : 

“ Failed to call GetTypes on assembly Microsoft.Office.InfoPath.Server, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c. Could not load file or assembly ‘Microsoft.Office.InfoPath, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c’ or one of its dependencies. The system cannot find the file specified. “

This left me nuts for couple of hours. We were working as a group and my idea was to reinstall Sharepoint and check if the problem existed before Office 2013 installation also. Because this made no sense to me. But a colleague of mine did some googling and suggested the below fix referring to here

Resolution

Uninstall Microsoft InfoPath from the Office 2013 Suite. It looks more like a compatibility issue of Sharepoint 2010 with Microsoft Office InfoPath 2013.

We did this and that helped. I was able to create new web applications :-)
