The MsiSetInstallLevel function returns one of the following values:

Remarks

The MsiSetInstallLevel function sets the following:

  • The installation level for the current installation to a specified value.
  • The Select and Installed states for all features in the Feature table.
  • The Action state of each component in the Component table, based on the new level.
For any installation, there is a defined install level, which is an integral value from 1 to 32,767. The initial value is determined by the INSTALLLEVEL property, which is set in the Property Table.

If 0 (zero) or a negative number is passed in the iInstallLevel parameter, the current installation level does not change, but all features are still updated based on the current installation level. For more information, see Calling Database Functions From Programs.

If the function fails, you can obtain extended error information by using MsiGetLastErrorRecord.
