When trying to upgrade agent on Windows 2008 R2 , the following error message is been received despite the Agent being stopped and no jobs running on the Agent server:
" The target : <agent_install_path>\cybAgent.exe is not writeable file. Terminating patching (java.io.FileNotFoundException: <agent_install_path>\cybAgent.exe (The process cannot access the file because it is being used by another process))
This seems to be a bug on windows 2008 machines:
WAAE Â Agent 11.3.6 SP7 on windows 2008 R2 serverÂ
To overcome this issue and upgrade the Agent on your windows 2008 R2 server, enable the "Application Experience" Windows service and run the installation again.
