Issue/Introduction



When installing .Net Agent , we get a popup box. It states -- "Version 8.0 or later of this product is already installed. Installation of this version cannot continue. To remove the existing version of this product, use Add/Remove Programs on the Control Panel." What should we do to resolve this and install the .Net agent?

Environment

All APM releases. 

Resolution

Delete these keys from the Windows Server registry using Regedit
 
HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\Introscope\NETAgent
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ComputerAssociates\Introscope\NETAgent (64bits machine)

The install should then be able to proceed.
