All questions related to installations, configurations and maintenance of Advanced Host Monitor (including additional tools such as RMA for Windows, RMA Manager, Web Servie, RCC).
We cannot reproduce the problem on our Windows Server 2008.
What application do you use to install RMA as service? RMA_CFG.EXE?
Are you sure you have necessary rights?
I verified I was logged in using an enterprise admin account. I still needed the "Run as administrator" to get it to work due to user rights escalation in 2008.
