With regards to files that don't have Version resources (since WiX's binder by default does populate the file hash for files that don't contain version resources) the following pages are of use to help you understand what is expected.
The default behavior for your case is described on this page: http://msdn.microsoft.com/library/aa370532.aspx REINSTALLMODE is described here: http://msdn.microsoft.com/library/aa371182.aspx The default value for REINSTALLMODE is documented as "omus". Additional information about file replacement rules (versioning) covering additional cases is found in the same area of the MSDN library. -----Original Message----- From: Miller, Craig [mailto:craig.mil...@spatialminds.com] Sent: Wednesday, June 30, 2010 11:55 AM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] Component Level Versioning? Thanks Peter and Pally for the replies. I don't make a lot of installers, but I did read and follow the component rules very carefully when I created the original installer. What I'm unclear on is if I have the same component snippet in two MSI files (same GUID), but one snippet contains a newer version of the underlying file, how does the windows installer know that the newer version is in fact a newer version? E.g. Version 1 created in 2008 and Version 2 created in 2010 are identical except the "Source" attribute of the "File" element points to an updated version of the file "..\USGS Topographic\250k\NY\c43078a1.tif". Since components don't appear to have any version info, if I run the version 2 installer, followed by the version 1 installer, what prevents the old file from overwriting the newer file? <Component Id='c43078a1.tif' Guid='784351B6-50BC-43B3-B668-F5248B4A4B90'> <File Id='c43078a1.tif' Name='c43078a1.tif' DiskId='1' KeyPath='yes' Source='..\USGS Topographic\250k\NY\c43078a1.tif' /> </Component> Agreed, VMs are very helpful for this sort of thing.
