Error chaining 2 MSI files

Jan 27, 2011 at 3:13 AM


I have a bootstrapper that has to install three requisites:

- .NET 4.0 (web installer, a .exe)

- One MSI containing a Windows Service. Installer generated with VS Setup project following this instructions:

- One MSI with my application. Another installer generated with VS Setup, just copies some files to a folder.

When I launch the bootstrapper, everything starts right: .NET downloads and installs, and the Windows service installs too. But then, when the second MSI is running I get this error.

Error 1001. Process must exit before requested information can be determined.

And the installer returns to the bootstrapper UI. If I try to install it again (without exiting the bootstrapper) then it works. Any idea what may be happening?

Is this error a popup from dotNetInstaller? If so, file a bug with a log file and as much detail as possible about this. DNI waits for msiexec to terminate and then figures out what the exit code was, but I am wild-guessing this isn't happening in this particular case for whatever reason. I've never seen this before btw.

I've added a bug with the logfile:

As I say there, the problem doesn't happen 100% of the time, not sure why. The machine is always exactly the same. Installing both MSI by hand doesn't give problems. Hope it helps, regards!

This is an error from your MSI. Change the command line arguments for EnterVolSetup.msi to log an output, /l*v <location of log file> and examine the log.
