IsPreventDowngrade: displays dialog with "1:" text only
Hi,
I´ve added a Major Upgrade and ISPreventDowngrade item to my Basic MSI project.
Launching a downgrade installation display a dialog with a simple "1:" text string. Did I missed something or is there a string missing in the string table?

I'd check the message with the type 19 error action, and any string IDs associated with it. I agree the symptom looks like it's getting an empty string (which then formats to 1: ). "
Found it by looking at a new project. IDS_PREVENT_DOWNGRADE_EXIT was missing in the string table.
Thanks for the type 19 error action hint, will try that in the future.
