All the CommonFilesFolder values in merge modules are by convention appended with a mangled guid, but as far as I can tell the mechanism that rationalizes all the folder name properties from merge modules (such as CommonFilesFolder.guid) at merge time is indiscriminate. If the folder name from the merge module *starts* with a standard folder property then the merge generates a CA to set it to the actual CommonFilesFolder. So when it gets merged into the MSI file it generates that type 51 custom action to set CommonFilesFolder<anything at all> to [CommonFilesFolder].
So yes, you're right, it is a really bad thing to use folder names in merge modules that start exactly like an actual folder name.

I'm getting some behaviour which surprised me... if I have the following in a merge module <Directory Id="CommonFilesFolder"> <Directory Id="CommonFilesFolder_A" Name="A"> <Directory Id="CommonFilesFolder_B" Name="B"> <Component Id="test.txt" Guid="*"> <File Id="test.txt" Source="d:\temp\test.txt"/> </Component> </Directory> </Directory> </Directory> then when I build an installer using this merge module, I get a number of messages like light.exe(0,0): warning LGHT1076: ICE82: This action CommonFilesFolder_B.E2FF78A9_BB72_4A5F_A259_16A004F2BFDF has duplicate sequence number 1 in the table InstallExecuteSequence and the file test.txt is installed directly in the CommonFilesFolder (rather than in the subdirectory A\B below it). If I change the Ids of the subfolder Directory elements to <Directory Id="CommonFilesFolder"> <Directory Id="XCommonFilesFolder_A" Name="A"> <Directory Id="XCommonFilesFolder_B" Name="B"> <Component Id="test.txt" Guid="*"> <File Id="test.txt" Source="d:\temp\test.txt"/> </Component> </Directory> </Directory> </Directory> (i.e insert an 'X' at the start), then I get no warning messages, and the file test.txt is installed in the correct location. Are there some Id name rules I'm not aware of? -- Cheers, John ------------------------------------------------------------------------------ Return on Information: Google Enterprise Search pays you back Get the facts. http://p.sf.net/sfu/google-dev2dev _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users *** Confidentiality Notice: This e-mail, including any associated or attached files, is intended solely for the individual or entity to which it is addressed.
