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After uninstalling a newer version of the client-side package, then reinstalling a previous version of the client-side package, the client application fails to instantiate the server component running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 is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Microsoft Transaction Server version that contains this hotfix.

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 about support costs, visit the following Microsoft Web site:

http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The typical support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

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 that this is a bug in the Microsoft products that are listed at the beginning of this article.
