Cause

Coldfusion is installed prior Pem Agent installation. Coldfusion variable (C:\ColdFusion9\verity\k2\_nti40\bin) prevents Pem agent installation.

Resolution

Check Coldfusion variables as below:

    C:\Users\Administrator>set |findstr /i cold
    Path=C:\ColdFusion9\verity\k2\_nti40\bin

When you install Pem agent, system unpack PAgent package to special directory and tries to use libraries from this directory. But as you have system variables, system tries to find libraries in system variables first. In our case, ACE.dll exists in C:\ColdFusion9\verity\k2_nti40\bin and in Pem agent installation directory as well. So system tries to load ACE.dll from C:\ColdFusion9\verity\k2_nti40\bin.

To solve the issue:

1. Remove Coldfusion variables path in system variables.
2. Reboot Windows Service Node.
3. Launch task for Pem agent installation once again.
