I think I recall you sometimes have to reboot and/or restart the Msiexec service after setting MsiBreak because the Service Control Manager doesn't get the env update. I haven't used it in a long time so I could be wrong. on the C#/DTF side I tend to use MessageBox during intitial development and almost never need to debug a custom action later in it's life cycle.

You may be able to set the breakpoint after the MessageBox and then attach to the running msiexec process. -----Original Message----- From: little.forest [mailto:little.for...@ymail.com] Sent: Tuesday, August 24, 2010 5:12 PM To: wix-users@lists.sourceforge.net Subject: [WiX-users] How to debug CustomAction DLL Dear Wix Experts: We have a CustomAction DLL written in C. How to debug it? There are a few posts about it: Post1: http://www.davidmoore.info/2010/06/28/how-to-debug-a-windows-installer-custom-action/ Post2: http://blogs.msdn.com/b/astebner/archive/2005/06/17/430320.aspx Post3: http://msdn.microsoft.com/en-us/library/aa368264(VS.85).aspx I tried it in Windows 7. I did set MsiBreak, but that famous "message box" never showed up. So I tried it in XP, the "message box" showed up. It says "To debug your custom action, attach your debugger to process 5632(0x1600) and press OK". I opened Windbg. Post1 says "attach the process", Post2 says "Open Executable...". I tried both, neither works for me. In both cases, I got "*** ERROR: Symbol file could not be found. Defaulted to export symbols for C:\WINDOWS\system32\ntdll.dll - ntdll!DbgBreakPoint: 7c90120e cc int 3" in Windbg. Questions: 1. What's the problem here? 2. Should I attach process? Or should I "Open Executable..."? 3. If I should attach process, why it doesn't work? 4. If I should "Open Executable...", what the "File name" and "Arguments" fields should be? For example, the "File name" should be "C:\Temp\MyApp.msi" or "C:\Windows\system32\msiexec.exe"? How about arguments? Should it be "/i C:\Temp\MyApp.msi"? 5. Why it doesn't work in Windows 7? If you even debug DLL CustomAction, pls let me know. Thanks!
