In a Microsoft Host Integration Server 2009 environment, you start the Transaction Integrator (TI) Manager MMC snap-in, and the MMC snap-in may close unexpectedly. This behavior occurs when Type Library (TLB) or .NET assembly files that the Transaction Integrator objects reference are not located in the correct folders on the system. When the TI Manager MMC snap-in closes, you receive an MMC access violation error message that resembles the following:

Application name

Application version

Module name

Module version








This problem occurs because Transaction Integrator does not verify that the TLB or .NET assembly files exist when the TI Manager MMC snap-in opens and tries to initialize the files.


The hotfix that resolves this issue is included in cumulative update package 2 for Host Integration Server 2009.

For more information about how to obtain the cumulative update package, click the following article number to view the article in the Microsoft Knowledge Base:

2645939 Cumulative update package 2 for Host Integration Server 2009


To work around this problem, copy the missing TLB or .NET assembly files to the correct folder that the the TI objects reference.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
