When you attempt to upgrade from SNA Server 3.0 using Back Office Server 4.5, the following error message occurs when you select to install SNA Server:

The previous version of SNA Server must be uninstalled before selecting this component.


To work around this problem, run the SNA Server Install program separately from compact disc number 7, where the SNA Server Install directory is located. The SNA Server Install program starts correctly from this location.
