Hi @Piotr,

Are you on K2 5.3 November CU?

If you are, please have a look at this post:
 

I believe you are looking for the 5.3 November 2020 CU Fixpack 6 which I will attach. If it is not the fixpack you are looking for or you are not on the November CU please let me know.

I’ve K2 Five (5.3) April 2020 CU Fixpack 21 installed. I wonder if there is a newest CU?

Kind regards,

Piotr

Hi @Piotr,

The Novemer CU is the latest for 5.3. You will be able to find it on this post as well as instructions on how to install it (if needed):
 

I will also attach the setup file here. If you have any more questions please do ask. Hope this helps :)
