That is why we encourage everyone to be very careful with component guids and when possible install to private locations.
If you have several products which share some common files, you don't need merge modules to achieve that. Just ensure that you author those common components once and share the resulting wixobj/wixlib files amongst all the products during linking.

A file will be deleted from disk and registration information orphaned when that file is installed by 2 different installers (in the same directory) using 2 different component GUIDs. I'll be at the funny farm for a bit. Sorry for the confusion Eric.

I read the blog(s). If 2 unrelated installs install the same shared file (say comctl32.ocx) both the installs need to use the same GUID for the component that contains the comctl32.ocx file so that reference counting isn't thrown askew? And if that is the case then the comctl32.ocx author's merge module must be used by all parties so they keep the same GUID. WOW. That means any installation that I put together must use merge modules from the shared file authors. And in my little bit of experience in creating installers I have found that the merge modules have quirks and bugs that I can't wait on them to fix and must create my own merge module that installs the shared file. Correct me if I'm wrong (and please be wrong) ... because if I'm not then this isn't so much a technical decision as much a business decision ... the decision being do we use technology on which our productivity depends on the productivity of a 3rd party.

It is very, very difficult to do correctly in all cases. You may be able to create specialized solutions targeted for your needs... but a solution that works for everyone every time is a lot more involved (and, I believe, requires storing data in ways that are rather unnatural in a build environment). -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rob Mensching Sent: Wednesday, August 09, 2006 10:03 AM To: 'Dave Williamson'; 'Eric Fesh'; wix-users@lists.sourceforge.net Subject: Re: [WiX-users] Request for Advice regarding File Organisation It can be worse than that. If any of those Files are shared across different Products that can be installed on the user's machine, you can get into scenarios where the Files are incorrectly reference counted.
