MBS: Client DPA Setup Error "Cannot Modify Registry Error -1"

ID: Q169211

The information in this article applies to:

SYMPTOMS

The Distributed Password Authentication (DPA) client upgrade for Microsoft Internet Explorer fails, and you receive the following error message during installation: 

   Cannot modify registry error -1

CAUSE

The DPA installation tries to modify a flag in the following registry key: 

   HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Security
If the key is absent, Setup generates the error message and fails to finish. The DPA upgrade is installed so that DPA will work, however MSN (The Microsoft Network) is not supported.

This also occurs if the Security Providers Value (which is also located in the preceding registry key) is missing.

WORKAROUND

Reinstall Microsoft Internet Explorer version 3.02 or later and then run the DPA upgrade.
