Our software requires SQL Server Express 2008 to be installed on various computers. We have run into a problem with systems that have WOW64. When the SQL installer is going through it's check list, it marks the WOW64 as the reason that it cannot continue. In other cases I get a notification that tells me that windows installer 4.5 or higher is required but when I try to install windows installer 4.5 it tells me that the it is not the correct verson of windows installer for the system. I try a few different versions and get the same problem. I am confused as to why one windows software would not work with another.
