If you receive an "incompatible driver" error while installing Capture One on Windows 10 or 11, it’s likely caused by an old Phase One driver left over from a previous installation.
How to Remove the Driver
1. Open File Explorer and go to:
C:\Windows\System32\DriverStore\FileRepository
2. Delete the folder starting with p1c1394.inf_amd64.
This driver is no longer needed and may block installation. Once deleted, you should be able to continue installing or activating Capture One.
Optional: Remove via Command Line
If you prefer using the command line:
- Open Command Prompt as Administrator.
- Run the following to list drivers:
pnputil.exe -e
- Find the entry for p1c1394.inf and note the OEM number (e.g., oem18.inf).
- Remove it with:
pnputil.exe -d oem18.inf
(Replace 18 with your actual number.)
