Sorry, used name on another post. Haven't used this forum previously and new. Anyway, didn't give you enough info. Using FSX SE. I installed the RealityXP GNS530 addon on other aircraft and it works. The Alebea GNS530 that came with the Saratoga works as installed but, when I attempt the RealityXP addon, I get this message in the middle of the screen with a folder box that states "Action can't be completed because folder/file is in use in another program. Close folder/file and try again" As far as I know, I have no other folder open that would conflict. I shut down the virus pgm also. The procedure I use the to execute the addon as with the other aircraft. I click the addon button on the FSX menu bar and then the Reality530 button to get the drop down menu. I select "Auto detect" and then 530 on #1 and accept. Then I get the error message.
Any help appreciated.
P.S. I sent another msg on a different forum. Didn't realize how to get your response.
