Symptoms

K2 Package and Deployment tool throws exception when we open any *.kspx file and processing/analyzing is started. The problem occured most likely after windows updates.

The exception which occurs is:

Diagnoses

Please verify if .Net Framework 4.6 or 4.6.1 is installed as per documentation below:

https://msdn.microsoft.com/en-us/library/hh925568(v=vs.110).aspx

As K2 blackpearl 4.6.9 does not support .Net Framework 4.6 .

Resolution

Rollback of .NET Framework should help resolve the issue.
