Environment Problem with V3.10

Hi All,

I have been successfully running all of the v3.X SDK Versions on my PC however now after installing V3.10 I am having problems with the new evironment variable for the Core Software path. The Open AT Settings page will not let me set this address to C:\OpenAt\Tools\CoreSW which is where the coresoftware is installed (even though I can see the core software dwl files in that directory! Anyone else had this problem? It is preventing me even creating a project with 3.10.

Kind regards,
