Hello @Anonymous,

I would first do a clean uninstall.

Please refer to this AKN article for information on how to perform a clean uninstall.

Then I would download the software you need using the Virtual Agent.

Please refer to this AKN article for information on how to get previous version software.

Here is a step by step instruction on how to get your software.

Please let me know if this helped you to solve the problem.
