The information in this article applies to:

Microsoft Exchange Server, versions 4.0, 5.0, 5.5

IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SUMMARY

When you run Setup.exe from the Microsoft Exchange Server compact disc, a message is displayed:

Setup is searching for installed components.

The Setup program is looking for an installation of the Exchange Server services and other related information in the registry.

MORE INFORMATION

To detect a previous installation of Exchange Server on your computer, the Setup program checks the HKEY_LOCAL_MACHINE subtree under the following subkey:

\Software\Microsoft\Exchange\Setup

The settings in this registry sub-key are similiar to this:

AdminDest: REG_SZ : C:\EXCHSRVR\BIN
MSMailConnector: REG_SZ : C:\EXCHSRVR
Internet: REG_SZ : C:\EXCHSRVR
Services: REG_SZ : C:\EXCHSRVR
X400: REG_SZ : C:\EXCHSRVR

NOTE: C:\EXCHSRVR is the default path, but the path can be changed and the settings in this registry sub-key display the actual installation directory selected during Setup.

To Hide a Previous Installation of Exchange Server from Setup.exe

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

If you want to prevent Setup from successfully detecting a previous installation of Exchange Server, perform one of the following steps:

Select the SETUP key and save it to a file, and then delete the key.

Temporarily modify these settings by completely removing the path.
