The addons I use on the regular basis are in the Community Folder and I have no problem in updating the Airac. This is the case for my PDMG 737-700.
I have other addons on a second SSD and they are linked to the Community Folder using MSFS_Addon_Linker.
I recently bought PMDG 737-800 from PMDG and installed it on this second SSD.
Unfortunatly I cannot update its AIRAC as I always have an error message although all my permissions are correctly set.
How to proceed as I’m not really comfortable in moving all my addons on my main HD.
