I finally installed SRM successfully.
I'm not really sure why there was this behavior.
I was working from a VPN connection. And even when I was connected to servers via Remote Desktop Connection SRM tried to download the plugin on my laptop because...
Maybe because I was not in full screen mode...
When I downloaded the exe file for the plugin on the server, everything worked fine...
Don't have a real answer to this problem.
I'm currently in the middle of a real test with SRM. Failover went fine but failback was a nightmare...
I will open a new post.
Thanks again guys.
Peace
