[wix-users] uninstall older InstallShield app

[kurt.jensen at us.ophiropt.com]

Alan,

Ended up splitting the custom action into two parts – detect old version and ask user if they want to proceed, and uninstall old version in a deferred custom action in order to get elevated privileges.

First part worked great, second part never did work right on every test system.  Finally the decision was made to simply prevent the new install if the old software was present. It now displays a message saying the user has to uninstall the old before being allowed to install the new.

Did you figure out a solution for this?
I just posted a similar question to the list, about removing product installed with InnoSetup

Our original app was written using Borland C++ 5.02 and installed with InstallShield 6.31.  :)

Service wants us to uninstall the old app with a prompt for the user during installation of the new app.





Initially wrote a custom action to throw up a message box then use registry entries to uninstall the old app.  Custom action runs immediate because the user must approve removal of old app in order to install new app.



Tried debugging the custom action. No exceptions.  No errors.  No idea if anything ran or not. Old app not uninstalled.





Tried breaking custom action into two parts:



1) Determine if old app is installed, ask user if we can uninstall, return ActionResult.Failure if No, runs immediate

2) Uninstall old app using inform registry entries, runs deferred with Impersonate="no" to get elevated privileges(?)



Again, no exceptions, no errors, not uninstalled





What would be the best approach to:



1) Determine if the old app is installed

    a) Ask user to uninstall. quit if they answer No, uninstall old app if they answer Yes

2) Install new app.





TIA!
