If you really need best compression don't pack the files with WiX in a cab but leave them separate (Compressed="no") and afterwards use 7zip ( http://www.7-zip.org/download.html -> 7z Library, SFXs for installers, Plugin for FAR Manager) and compress them with a sfx header as self extracting exe. Think then the packing should be better than playing with the CompressionLevels in WiX.
If you don't like the Program Compatibility Assistant appearing after running a 7zip exe on Vista ++ embed a admin manifest with mt.exe into the sfx file from 7zip. BTW afaik you can use different compression settings on each file. Check my posts http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Change-CAB-compression-level-without-rebuilding-CABs-td5918482.html . cabOut.PackFiles(tempDirectoryTempFolder, sourceFileList, fileList, Microsoft.Deployment.Compression.CompressionLevel.None, null); should be configurable for each filelist with different CompressionLevels. 2011/1/18 Pally Sandher <pally.sand...@iesve.com>: > WiX sources are widely available, knock yourself out. > > Palbinder Sandher > Software Deployment & IT Administrator > T: +44 (0) 141 945 8500 > F: +44 (0) 141 945 8501 > > http://www.iesve.com > **Design, Simulate + Innovate with the <Virtual Environment>** > Integrated Environmental Solutions Limited.
