Non-Administrator installation of Db2 Connect (Windows)

There are some additional considerations when you install Db2 Connect on Windows operating systems using a non-Administrator user account.

For a non-Administrator's installation, the account you are logged on as must belong to Power Users group.

Some information about Db2 Connect that must appear in the registry must be entered in the HKEY_CURRENT_USER folder in the registry. Although many items will be stored under the HKEY_LOCAL_MACHINE folder in the registry for non-Administrator installations of Db2 Connect, the environment settings must be changed in HKEY_CURRENT_USER.

A member of the Windows Administrators group must configure the Windows elevated privileges settings to allow a non-Administrator user account to perform an installation.

Note: If a non-Administrator user account is going to do the product installation, then the VS2010 runtime library must be installed before attempting to install a Db2® product. The VS2010 runtime library is needed on the operating system before the Db2 product can be installed. The VS2010 runtime library is available from the Microsoft runtime library download website.

System shortcuts must be changed to user shortcuts for the non-Administrator install. Moreover, since services are required to install any of the Db2 Connect products, but cannot be created without administrative authority, services that would be automatically started are run as processes when a non-administrator installs.

The following scenarios are installation situations that you might encounter in an environment where both administrator and non-administrator installations exist:
  • A non-Administrator has installed Db2 Connect, and then an Administrator attempts to install Db2 Connect on the same system. The Administrator will get a message that the product is already installed. The Administrator does have the authority to uninstall and reinstall the product to get around this issue.
  • A non-administrator has installed Db2 Connect, and then a second non-Administrator attempts to install Db2 Connecton the same system. In this scenario, the installation will fail, and return an error message that the user must be an Administrator to install the product.
  • An Administrator has installed Db2 Connect, and then a non-Administrator attempts to install Db2 Connecton the same system. In this scenario, the install will fail, and return an error message that the user must be an Administrator to install the product. An Administrator always has the authority to uninstall or reinstall.
