FMGS A320 not showing in FSX

Requesting help in FMGS basics..I have recently installed Jeehell FMGS (B47) on PC with W10 and FSX. I have also installed FS Labs A320 in FSX. However, the FMGS A320 is not reflected in the choice of ac in FSX. How do I select the FMGS ac in FSX? Do I need to uninstall FSL A320? FMGS is installed in the default folder C: \A320FMGS and FSX is in the C:\Program Files(x86)\ Steam.

You don't need to uninstall any other aircraft. Did you do the install with administrator rights?

Thanks for the help. I uninstalled FMGS and then reinstalled with Adm rights but still no joy. Could it be a registry problem?
