Installing on Windows 2000 using Terminal Services

It is possible to get errors when installing WebSphere® MQ on this configuration. Microsoft® KB article 255582 explains:

"When you are installing a Windows® Installer-based setup program from a Windows 2000 Server Terminal Services session, you may receive one of the following error messages (where myapp.msi is the name of the .msi file that you are running).

On a system running the base version of Windows 2000, you will receive error 2755: Internal Error 2755. 3 \myapp.msi.

On a system running Windows 2000 Service Pack 1, you will receive error 1305: Error reading from file: \myapp.msi. Verify that the file exists and that you can access it.

CAUSE:

These errors occur if you're running from a Terminal Server session and the path to the installation files is a mapped drive. The Windows Installer service is running in a different session than the user and therefore has different drive mappings. The errors occur because the .msi files that are needed cannot be found.

RESOLUTION:

To work around this problem, use the full universal naming convention (UNC) path on the command line or run the installation from the Terminal Server console."

Note: On WebSphere MQ the .msi file name is either "IBM WebSphere MQ.msi" or "IBM WebSphere MQ Extended Transactional Client.msi". The UNC is of the form "\\<ServerName>\<ShareName>setup.exe" where <ServerName> and <ShareName> are the appropriate values for your machine setup.
