It could make an interesting custom action. Microsoft CAB supports extracting files from any source (disk, stream, memory, etc.). Elmue's cablib (http://www.codeproject.com/KB/files/CABCompressExtract.aspx) knows how to deal with all of it, for example how to extract single files from a CAB embedded as a resource. You could add an implementation that extracts the file directly from the embedded CAB in an MSI without extracting the whole thing first.
Some C++/C# work required :) dB. @ dblock.org Moscow|Geneva|Seattle|New York -----Original Message----- From: Niklas Söderberg [mailto:niklas.soderb...@gmail.com] Sent: Thursday, May 06, 2010 3:40 AM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] Read file content from CA Thanks for your suggestions, but I guess I didn't emphasize enough that I need to read the file in an _immediate_ custom action, that is, I need to read it from the installation package before the file gets installed. I guess there's no easy way to do it, so the way I solved it was to temporarily extract the embedded cab-file and from there extract the file I need. A bit cumbersome, but it works.
