The only reason I asked is because the guid that suffixes the property names is supposed to be the MSM's Package @Id, and there should be no reason that your MSM is using another MSMs properties. However, that appears to be a red herring (the "duplicate sequence number" warnings are expected in that scenario). The purpose of the duplicate sequence warnings is to make you look to ensure that there isn't any sequencing expectation between the actions being merged. Setting the values of the system directories doesn't generally have that concern.
The concern I see looking more closely at your build spew is the "action [that] cannot be merged" report. Are the names of the actions really blank ('') or did you remove the action names? If you look at your MSM in Orca (or other MSI viewer/editor), does it really have entries in the sequence tables with blank or missing action names? Does your MSM pass validation by itself?

Subject: Re: [WiX-users] Visual C++ 2010 Merge Module If you mean if I've used guids which are also used in the VC MSM, then no. I've tested this by generating completely new guids for my merge module, and still I got the warnings. Thanks for the idea though, didn't think of this obvious error... -----Original Message----- From: Blair [mailto:os...@live.com] Sent: Monday, January 30, 2012 9:07 AM To: 'General discussion for Windows Installer XML toolset.'
