Rather than prompt the user to do the uninstall, have you considered having MSI take care of it for you? How to make that work is reasonably well documented at http://blogs.technet.com/alexshev/archive/2008/02/15/from-msi-to-wix-part-8-major-upgrade.aspx. Note that this requires you increment one of the first three pieces of the product version, not the last piece, for detection to work properly (i.e. you have to roll from 1.2.10.1 to 1.2.11.0).

Hello Everyone, I have a question on how to popup a warning mesagebox if there is old version already installed. I will appreciate any help. Backround: e.g, I have installed a product with version 1.2.10.1. Now I have a installation with a higher version 1.2.10.2 When I double the product.msi, the maintaince page is shown up and ask me to repair, modify or remove the product. However, I don't want this page shown up but only a message box pop up and give a warning message "An old version of this product is already installed. Please use the Add/Remove to remove the product first and then install it again." Then the installation wizard exists. Could you please give me a hand?
