Client Security 12.20 installation causes big problems with some applications

Hi

 

We are using CS 12.00 with deepguard and internet shield. I updated to version 12.20 and now there is many problems with applications.

 

Outlook 2013 / or Lync is closing and opening repeatedly. Or connection is breaking?

One special application is not printing anymore.

Maybe some random problems with Citrix receiver too but this is not for sure.

 

If i remove 12.20 and install 12.00 everything works ok with same settings? Workstations are Windows 7 x64 Finnish.

 

I have to roll back some 40 laptops because this is causing major problems in our production environment.

Hi

 

Looks like this is same problem -> https://community.f-secure.com/t5/Known-Issues-in/User-experiences-various/td-p/86044

 

Changed stateful inspection level from disabled to RFC and at the moment it is fixing this problem as far as i know.

 

Seems that setting this to disabled in 12.20 causes network connection interruptions ? Looks like almost all applications that use network are suffering from same kind of problems.
