That location was listed as well when I researched it. I've always thought that the local machine setting took effect for all users though so it would be best to look at.

>>>Any advice please on where I should be looking instead or where else I should be looking. The ShellExecute works fine and it does pick the right client so it must be lodged some, any ideas will be much appreciated.
