Check if Windows Installer is ready to run
Hi there,
Does anyone know of or have any code that I can use in a Deferred in System Context, Asynch - No Wait custom action that I can use to check if the MSI engine is ready to run another installation.
You may have seen my post about chaining a 64 bit installer to a 32 bit installer. Well, that won't work for us...
So, what I'm doing now is actually installing a 64 bit installer with our 32 bit app. On a 64 bit machine, a Custom Action widget compiled for x64 fires and installs/removes on uninstall the 64 bit pieces. All seems to work OK, but at times I get the 'another installation is in progress' message when the 64 bit installer runs.
What I've done just to get a build to QA was to add a 30 second pause in the Custom Action widget which allows the main or calling install process to clear. Clunky, I know so I want to replace this with some code to monitor the Installer engine to see when it clears for my second installation.
I found this, but I'm not a C or C# guy so VB.NET code or any other information would be greatly appreciated...

I created a custom action widget that fires Asynch-No Wait. It monitors msiexec processes until the instance count is <=1. The widget will then fire the 64 bit install package installed via the 32 bit main install.
It may be clunky, but it seems to get the job done.
