Have been stumbled upon a very unusual issue - after MS Office installation all web applications (bad practice, i know), including central admin, return a 503 error. Reason is application pools in stopped condition. Any attempt to start up application pool fails.
There are no errors in Sharepoint Logs - only in event viewer. This and this

The Module name SharePoint14Module path C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\isapi\owssvr.dll returned an error from registration. The data is the error.
I looked up a little bit - Enable 32-bit application is set to false, manipulations with ApplicationHost.config doesn't bring anything.
Does anyone have any idea what is source of this troubles?
Thanks in advance!
