Challenge

Veeam ONE installation fails with "Couldn't create crypto provider" message.

Cause

One of the known issues with Microsoft update 3000850 as per this MS KB article is the following: Opening Credential Manager fails with error 0x80090345", that also affects creating crypto provider.

Solution

To work around this problem, set the value of the ProtectionPolicy registry entry to 1 to enable local backup of the MasterKey instead of requiring a RWDC in the following registry subkey: HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb
