Isn't it possible to change the installer that it verifies all the certificates before it starts to copy and installing all software?
Right now you need to specify you cert,key,CA , next it starts to install (15-20min) and then it may tell you that there were some issues during installation because there was something wrong with your certificates. Waste of time ;(
We also encounter some high CPU utilization with the Adaptive agent on windows XP clients. Machine becomes slower after we installed the agent.
Keep up the good work!
