[wix-users] WiX Installer hangs intermittently while executing custom action

Hey Russell,

Thanks for your response. We have tried with the logging enabled and it happens only once in while. The log file contains log till the custom action is triggered and post that there is no error, just a hang issue. We are doing dacPac deployment in the custom action and there are 4 dacpacs that we deploy. Invariably it fails in the first or second deployment only and if it passes that sate, it completes the deployment without any issue.

I did Debugger.Launch() in the custom action and didn’t find any issues. Infact I added extra logging as well and even that didn’t indicate any issue either. If the code review would be helpful, I can share the custom action code.

Sorry, hit the wrong button. Have you tried it with logging turned on?

msiexec /i "my-installer.msi" /L*V "my-installer.log"

This might give you some reference, or might not be helpful at all.
Perhaps some indication in your email about what the custom action is
doing would be helpful to suggest debugging? A couple thoughts come to
mind: A resource is in use and can't be removed, a UI element has been
created to ask for information from the user and no UI is available.

Has the CustomAction been independently debugged?

Based on the analysis, the machines in which this issue occurred had not been restarted for 8-9 days. We analyzed the wait chain and found that msiexec was waiting for rundll32.exe. On killing rundll32.exe, the setup rolled back. Any pointers to get around this issue would be great as we are about to release this to customer
