Is the Winmor and WL2K all included in the RMSexpress, or is it separate software ?
As Richard said, Winlink (WL2K) is the system you want to access. Winmor is the sound card mode RMS Express uses to connect to WL2K stations. It is an option built into RMS Express, you don't have to install any other software. I installed RMS Express, told it to use the SignaLink device, went through the configuration and everything seemed to work the way it should.
I didn't have any problems installing RMS Express in Windows 7 - could you be having Windows compatibility problems, like maybe some of the new Windows 10 security signing requirements? I don't have Win10 so I don't know if there are any issues there.
