The UnregisterProgIdInfo action manages the unregistration of OLE ProgId information with the system.

Sequence Restrictions

The UnregisterProgIdInfo action must come after the InstallInitialize action, UnregisterClassInfo action, UnregisterExtensioninfo action, and before the RegisterProgIdInfo action.

RemoveRegistryValues must come before UnregisterProgIdInfo in the sequence.

The sequencing of the actions in the following group is restricted. If any subset of these actions occur together in a sequence table, they must have the same relative sequence order as shown:

• UnregisterClassInfo
• UnregisterExtensioninfo
• UnregisterProgIdInfo
• UnregisterMIMEInfo
• RegisterClassInfo
• RegisterExtensionInfo
• RegisterProgIdInfo
• RegisterMIMEInfo

For example, UnregisterProgIdInfo must come before UnregisterMIMEInfo in the sequence table.
