SPAPI_E_DRIVER_STORE_ADD_FAILED
SPAPI_E_DRIVER_STORE_ADD_FAILED (0x800F0247) is a Windows SetupAPI driver-installation error. This code means staging the driver package in the Windows Driver Store failed. The root cause is commonly an invalid INF, missing catalog, signature failure, inaccessible source file, or a package that is incompatible with the platform.
What to check
- Read the full signing and copy sequence in
setupapi.dev.logfor the first underlying error. - Verify that the package contains all files referenced by the INF and catalog.
- Stage one specific vendor INF with PnPUtil rather than bulk-copying files into system folders.
pnputil /add-driver "C:\path\driver.inf"
Microsoft: PnPUtil command syntax
Microsoft: Catalog files and digital signatures
