TweakFS have updated their SimSwitch utility with better Prepar3D V2 auto-detection and an expanded Help file that explains how to use it.
This utility switches the FSX installation folder path stored in the Windows Registry from FSX to Prepar3D (and back). This may help some FSX addons and their installers use the P3D folder as the target instead of the default FSX folder.
The editing of the FSX Registry key can of course be done manually using RegEdit but this tool makes it a quick and safe one-click step instead of a tedious search/replace operation.
Available from the TweakFS Free Tools page.
