MSI calculates the hash of data files and, if hash is different, patch will update the older file. However, that is only in the case that file creation and modification time&date are identical. When time & date are not identical, MSI assumes that file was touched by the user and won't patch it.
Thus I believe that modified file is in the patch, it is just that MSI doesn't apply the patch because of time & date. Verbose log can also confirm this - it is good to do a verbose log of patching process whenever reporting issues in any case. -----Original Message----- From: Oleksandr Y.

Subject: [WiX-users] How WiX resolve that file was changed when creates patch Hello, I've noticed one strange thing. When text file (for example html file) was changed but it's size wasn't changed it will not be included to patch. For example, if I change 2 symbols to other 2 symbols, WiX don't detect that file changed and not include it to patch. Are there way to force binary files compare? I use patch syntax like <Patch Classification="Update" MinorUpdateTargetRTM ="yes" AllowRemoval="no" Manufacturer="$(var.Manufacturer)" TargetProductName="$(var.Manufacturer) $(var.ProductName) $(var.ProductVersion)" DisplayName="$(var.ProductName) patch up to $(var.ProductVersion)." Description="$(var.ProductName) patch up to $(var.ProductVersion)."> <Media Id="5000" Cabinet="patch.cab"> <PatchBaseline Id="$(var.ProductAbbreviation)" /> </Media> <PatchFamilyRef Id="PatchFamily_$(var.ProductAbbreviation)" /> </Patch> <Fragment> <PatchFamily Id="PatchFamily_$(var.ProductAbbreviation)" Version="$(var.ProductVersion)" Supersede="yes"> <ComponentRef Id="Component.Name" /> ...... ---------------------------------------------------------- Best Regards, Oleksandr Y.
