fsx steam navaids update

Good day everyone. i recently installed fsx:se and need to update navaids. now when i try to update the region selector and i choose my fsx:se root folder i get a message invalid folder, unknown or inactive simulator. i am not sure how to proceed to fix this. This is on the world ils/runway update. the world navaid package worked perfectly with the fsx:se root folder. im not sure which folder to select 

regards
