Correct, that's how ARP works. Uninstalling from ARP shows only a basic UI so if something fails, your MSI package can't display authored UI. So ARP shows a message based on the MSI error code. A failed launch condition returns ERROR_INSTALL_FAILURE, which is "A fatal error occurred during installation." That's why I suggested a CA that returned ERROR_INSTALL_USEREXIT, which presumably would show the message "User cancelled installation." ARP doesn't let you customize the message that's shown, for better or for worse. You didn't answer my question -- you want the uninstall to be canceled; you just don't like the "fatal error" message, right? > Which leads me to your suggestion regarding the custom action that I > run. I have it set such that the return value is ignored. Don't set the continue attribute -- you want the return value to be acted on. -- sig://boB http://bobs.org ------------------------------------------------------------------------- Take Surveys.
