This message will occur under the following circumstances:-
1- The IRRICAD Link installation being installed is not compatible with the CAD version. Note, if you have more than one CAD version installed, to set the correct one as the "Current Version" first run it then close it before installing IRRICAD Link.
2. The second cause is due to the CAD version being installed when the user does not have Administrator privilege.
To ensure that required registry entries are present and the User files will be accessible when logged in as the normal user we suggest that the user be given Administrator privilege, if they don’t have it already, for the duration of the install. Note that BricsCAD or AutoCAD will also need to have been installed with the user's Administrator privilege. Using the Admin password when installing for a normal user will not provide the required registry entries, nor will installing when logged in as Administrator provide the correct files in the Users folder.
