Hi folks,

I'm rather new to Windows Installer development, so bare with me.  

I have a DLL imbedded within my installer which is checking the version of IE on the given user's machine.  If it doesn't match, I basically want the installer to jump to a cancel page, or an exit page, or whatever.  I thought I might be able to do this by calling MsiDoAction, but no matter what action I pass to that bad boy, I always get the following error:  ERROR_FUNCTION_NOT_CALLED.  I've tried running a couple of other MSI functions (MsiGetParameter for example) and haven't had a problem.

Any thoughts?

Thanks!

Suggestion

Your test dll sets a property.

You create a type 19 CA to indicate the error condition if the property is set.
------------------------
Alternately your dll can display a message using MsiProcessMessage and return ERROR_INSTALL_FAILURE.

Much appreciated Ian, I'll give those a go.

Many thanks, my friend.  That return code did precisely what I needed.  'Twas so simple I'm embarassed I didn't come to it myself.
