[wix-users] pass credentials to a service and retry if wrong

Sun Aug 9 22:10:15 PDT 2020

Is there any example of using ApprovedExeForElevation ?

I'm new to bundles so anything more than the element description would be
very helpful (google found little). I've followed "Building Installation
Package Bundles" in docs manual and hope to get further. From earlier
replies it seems the regular WixCA function WixShellExec won't do the
trick, but in general can an exe launched via WixShellExec discover the
install's UI level (perhaps only via registry key set by a CA?)

Other naive questions about bundle abilities .. if there's somewhere this
info is available please point me at it:
- optionally run silent, as well as with UI?
- pass command line parameters to the MSI and exe?
- change the UI so the install location is not an option?
- add dialogs to the UI
- change the uninstall UI to have only 'uninstall' (not 'repair')

Can WiX Standard Bootstrapper do these or can they be done with a
home-rolled bootstrapper DLL?

thanks again for all the help
Alan
