What is the User Access Control or UAC?

The UAC is a security feature in Windows Vista, Windows 7, Windows 8 and Windows 10 which helps prevent unauthorized changes to your computer.

When the UAC is on you will get a prompt to authorize the changes. This prompt does not work for background processes therefore the changes are automatically denied by the UAC.

For Sage Pastel and Pervasive to register correctly and apply the database licenses you will need to ensure that the Windows User Account Control or UAC has been turned off as these are backgroud processes that get denied and can lead to error code 20, status 161, Pervasive error code 94 etc.

The reason the UAC needs to be turned off is that during registration the licenses for the Pervasive database are applied in the background.
