I installed IPAM v4 on our Orion core server w/o issues. However, when I ran the poller version of IPAM on our polling engines, it aborts. The error message reads as follows:
SolarWinds Orion IP Address Manager Polling Compatibilty is already installed. To repair this installation, use the "?Add or Remove Programs" control panel.
I made sure that I used the correct file (i.e. SolarWinds-Orion-IPAM-v4.0-Full.exe) on our core server and also the correct file (i.e. SolarWinds-Orion-IPAM-v4.0-Poller.exe) on each of our 3 polling engines. I recieved the same message, telling me that the polling compatibility is already installed. However, when I check the Add/Remove Programs window for each of my polling engines, there is no trace of any SolarWinds applications with the name Compatibility or IPAM. Any ideas?
