The setup.exe program and the ProductConfig.exe program check for and install prerequistes as needed. 
They are copied to the install folder under C:\Program Files\ANSYS Inc\v{version}\prereq

It may be that 2022R2 is not installing the prerequisites, whereas 2022R1 is. 
A few possible reasons:
 – Pending reboot
 – Pending Windows Updates
 – Newer version of Prerequisite is already installed.
