Diagnoses
Upgrade to 4.6.9 - K2 Smartform Configuration Analysis gives error "Could not set key access: {0}"
Resolution
From the installer trace, it looks like the installation account "DENALLIXAdministrator" was not able to grant private key access to the K2 service account and possibly the K2 web application service account (same account). After giving the "DENALLIXAdministrator" Full Control on the "C:ProgramDataMicrosoftCrypto" directory and then performing a reconfigure, the Configuration Analysis no longer display this error.
