NTE_PROV_TYPE_ENTRY_BAD
NTE_PROV_TYPE_ENTRY_BAD means that the registration data for the requested cryptographic provider type is invalid. This points to a broken provider installation or corrupted configuration rather than an invalid plaintext or certificate.
Recommended response
- Record the provider name, provider type, account, and operating-system version before changing the system.
- Repair or reinstall the provider from a trusted package and verify its files and registration afterward.
- Avoid hand-editing security-provider registry data as a first response because it can make the configuration less recoverable.
