Hello Joannes,
The registry search values are only set once at startup of the installer, is that correct?
Yes, during the
"Searches" action group.
Is it possible to refresh the value of a registry search while navigating through the installer using a custom action or some event?
Yes, that is possible,
The result of your search is saved in the property that has the same name as the search, e.g.:
REGISTRY_KEY_ODBC_DRIVER_17_EXISTS
With that being said, you can use, at a later time in the installation, a
"Set property" event that should set the property to a new value.
Best regards,
Catalin
