Using RemoteApp as default program to open files

Hi Guys,

I know this has been covered before HERE, but i'm struggling and could use some help.

I've set up a 2012 R2 server which is serving up RemoteApps to users... all is good.

Now i need to use the RemoteApp as the default program for various file extensions.

Most of the client machines are Windows 7, so I know I cant do this in the normal way, so following an example given in the link above, I popped together the following .reg file which i've imported into my registry in an attempt to make my machine use the Word RemoteApp as the default program to open .docx files, however its not working.

There is no error given, it simply just doesnt do it....

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Classes\Word]
"AppUserModelId"="Microsoft.Windows.RemoteDesktop""EditFlags"=dword:00100000

[HKEY_CURRENT_USER\Software\Classes\Word\DefaultIcon]
@="C:\\cust_res\\Icons\\Word.ico,0"

[HKEY_CURRENT_USER\Software\Classes\Word\shell]

[HKEY_CURRENT_USER\Software\Classes\Word\shell\open]

[HKEY_CURRENT_USER\Software\Classes\Word\shell\open\command]
@="\"mstsc.exe\" /REMOTEFILE:\"%1\" \"C:\\cust_res\\Resource\\Word.rdp""

[HKEY_CURRENT_USER\Software\Classes\.docx]
@="Word"

[HKEY_CURRENT_USER\Software\Classes\.docx\Word]

[HKEY_CURRENT_USER\Software\Classes\.docx\Word\ShellNew]

Any help or direction you guys can offer would be greatly appriciated.

Thanks
