We also use a web based install (written internally) that looks at the one variable that is found in the 5 key, but not in the 4 key. If that key is present, the install does not execute.
During removal of the 5-key product, that one key does not get removed (if the 4-key product is installed). It doesn't matter which productr, the 5-key or 4-key, is installed first. It always happens.
When the user selects to remove the product from the Remove All in the dialog box or from the control panel, how can I remove this one key? I know I can write something in a script (which I am planning to do), but where do I insert this custom action in MSI 2.03?
Thanks.
