I am currently trying to find where I can find the installation instructions for CAPKI 5.2.4 for Windows for Automation Engine v12+
As from the tags & your post - this topic seem to be in regards to the Automic Workload Automation... As such I will moved this post from the CA Automic Community to CA Automic Workload Automation space.
Additionally, a quick search on the AWA manual on CAPKI, it show some information on its installation...CAPKI installations
Was this the information you were looking for? or is there more specific you are looking for in installing the CAPKI for the Automation Engine?
