BUG: Uninstalling a MTS Client Package Does Not Remove Typelib Registry Entries

ID: Q241377

The information in this article applies to:

Microsoft Transaction Server 2.0

SYMPTOMS

After uninstalling a newer version of the client-side package, then reinstalling a previous version of the client-side package, the client application fails to instantiate the server component running under Microsoft Transaction Server (MTS).

CAUSE

The MTS package uninstall does not remove the Typelib registry key for the newer version of the component, however, it does delete the actual type library pointed to by the registry key, making the value associated with this key invalid. When a client application tries to load the most recent version of the type library, it tries to load the type library that no longer exists.

RESOLUTION

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Microsoft Transaction Server version that contains this fix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information on support costs, please go to the following address on the World Wide Web:

Workaround

Install the hotfix on the computer where the client-side package is being exported, and then re-export the client-side packages. Use this package instead of the old ones. This hotfix removes the registry key along with the type library.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.
