Title: GSX Pro Won’t Install via FSDT Installer — Need Help
Post by: chatnyurur on December 01, 2025, 10:15:52 am

Hey everyone,
I’m having trouble installing GSX Pro. When I click the Install button inside the FSDT Installer, it downloads all the files, but once the download finishes, nothing happens. The installer just goes back to the same screen as if I never installed anything.

I’ve never had this issue before, but it started after uninstalling and reinstalling the program. Installing it on drive C or D makes no difference. Running the installer as admin didn’t help either.

GSX Pro simply refuses to install.
Would appreciate any help or suggestions. Thanks!

I just had the same problem after uninstalling GSX to do a clean install of version 3.7.3. To fix it, run the offline FSDT installer available on the forum, then at the end of that installation, run the live FSDT installer to install the last files. And that's it.

I solved the issue by running the installer as admin. thank you! :)
