Hi Chukwuemeka,
You may not need to uninstall on winsvr2. I'm assuming that you are referring to SQL not being installed the same on winsvr1 and winsvr2. As long as the basic installation path is the same for the SQL binaries but the Master Database is in different locations, VCS can correct this. However, if the path to the SQL binaries are not the same on winsvr1 and winsrv2, then you will need to uninstall/reinstall SQL so that the binary path is identical.
If you are talking about SFW-HA is not installed to the same path on all nodes, then I would recommend correcting this because you might get odd behavior as you try to do some cluster operations.
Thank you,
Wally
