I have used the uninstall application to uninstall once, i but it still doesn't work. Do I need to place the GSX folder in the same drive with p3d?
No, you shouldn't install GSX into the same P3D folder. However, maybe it's not clear to you what your problem is:
- Your problem doesn't anything to do with GSX. Nothing you do in GSX will fix this, because the problem is totally unrelated to it
- Your problem is caused by another product that has somehow caused SODE to stop working
- The reason why SODE say it cannot register itself, is because your P3D registry keys are wrong, because you MOVED P3D
- The product you must uninstall/reinstall is P3D, because the P3D registry keys need to be set correctly by its own installer
