Issue:We just installed the Privileged Identity Manager Endpoint on another 2 Windows 2008 R2 servers.
PIM 12.6+ Endpoint
The cause of this issue is based on the cainstrm service that runs with the PIM endpoint. It's job is to intercept all .net operations such as exchange and has an issue dealing with 64-bit services utilizing 32-bit libraries and the services will crash/not run.
Resolution:The tested solution for this issue is changing/creating if necessary, the registry value from 1 to 0 for key HKLM\SYSTEM\CurrentControlSet\Services\cainstrm\Parameters\DotNetOperationMode and attempting a restart should allow the services to start.
Release: ACP1M005900-12.6-Privileged Identity Manager
