I have MSFS 2020 and MSFS 2024 on two separate drives. I have a functioning GSX in MSFS 2020. I installed MSFS 2024 then ran FSDT Installer. I selected MSFS 2024 store to install GSX. It installed with version 3.3.4. When I launch MSFS 2024 I see no GSX in toolbar. The FSDT installer shows the proper Community folder for MSFS 2024. When I look into the COMMUNITY folder and compare it to what is in the Community folder for MSFS 2020, the 2024 folder has no fsdreamteam.... folders?
I have found a solution to my issue. My Community Folder is on an External USB SSD. The drive , as purchased, has a format of EXFAT. This format does not allow Symbolic Links, which GSX puts into the Community Folder. I had to reformat this drive as NTFS. I then did a check from the Installer, which then put the symbolic links into the Community folder. They are directory symbolic links.
