I’m busy with a new installation and getting an issue where the installer gets stuck on the below screenshot. The error in the install log is also listed.

I’ve checked the status of the VSS writers and they’re all healthy. The Windows Event log isn’t showing up any errors warnings either.I suspect this might be a permission issue, but I am a local administrator on the server

Have you AV running on the server ? if so disable and retry the install.

Error code 3 means “The system cannot find the path specified.”

So VSS_SWProv_SvcPS.dll is probably missing if I had to guess.

It could be that your install media is missing or damaged.

If you can find that DLL on your system/installer source, manually register it using an updated path and retry the install

regsvr32.exe" /s "C:\Program Files\Commvault\ContentStore\Base\VSS_SWProv_SvcPS.dll"
