Uninstalling 32/64 bit registry view question

rholdsworth · 4th February 2008, 00:43

My program allows both a 32 and 64 bit version to be installed and as such it is possible that info is in included in both registry views.

If a user has both versions installed, how can I tell in the uninstaller which version I am uninstalling so I know which registry view (SetRegView) to set in order to remove the correct keys?

Create a marker file in the installation directory or a marker key in the registry where it's not split into views.
