The Windows User Account Control (UAC) often blocks installers from writing to the C:\Program Files directory unless explicitly authorized.

Let’s tackle each of these causes with proven solutions.

Soundtoys V5 Preset location, presets not saving and hardlinks

: The installer or the DAW may lack the necessary administrator privileges to write data to the C: drive.

Locate both the TEMP and TMP parameters under user variables.

"cannot create Soundtoys version root folder at Soundtoys 5"

Cloud storage services like Microsoft OneDrive often hijack the standard local pathing system. If your Documents folder is hosted on the cloud, the plugin will look for a path that may not physically exist when the DAW boots up.

Are you encountering this error specifically or when opening a plugin inside your DAW?

Rescan your plugins. If the error persists, move to the manual folder fix. 2. Manually Create the Directory

Check if a Soundtoys folder exists. If it is missing, manually create a new folder named Soundtoys . Inside it, create another folder named Soundtoys 5 .

With these tools and knowledge, you can overcome this frustrating error and continue creating without interruption.

Use Cmd + Shift + G in Finder to navigate to /Library/Audio/Plug-Ins/ and manually delete the Soundtoys folder.

Running your DAW in standard mode while the plug-in requires administrator privileges to create folders—or running the DAW as an administrator while the public folder is locked to a standard user—will break directory access.
