Reinstalling MSMQ

You can reinstall MSMQ dependent clients, independent clients, and servers by running Setup from the Start menu. You can either add or remove a component (for example, the MSMQ SDK or administration tools), or simply reinstall all files. Reinstalling MSMQ does not affect your MSMQ settings or your Windows registry (unless the change is related to the addition or removal of an MSMQ component). You must close all MSMQ-based applications before reinstalling MSMQ. To reinstall MS DTC, Setup must stop the MSDTC and MSSQLServer services. Setup restarts these services after reinstalling MSMQ.

If you want to install a different MSMQ computer type (dependent client, independent client, or server) than you currently have installed, it is best to first remove your existing MSMQ installation.

When you reinstall an MSMQ controller server, Setup preserves the existing database and does not remove the local private queues from the computer's registry.

Note If you installed the limited version of SQL Server 6.5, MSMQ Setup does not reinstall it when you reinstall MSMQ. To reinstall the limited version of SQL Server 6.5, run SQL Server Setup.
