Limited account users of Windows XP Professional can not use CX-Motion unless they have read-write access granted to the program files. (This means, System Administrator has to grant read-write access to the CX-Motion folder and program files for users with Windows XP Limited account privileges).

This can be done following one of the options below:

Option 1 change User privileges (From Limited account -> to -> Administrator Account).
This option is always more simple and thus, more secure.

Option 2 is to change File & Folder security settings.
This option is not as easy as Option 1, and requires higher WinXP Administrator knowledge.
