Hi Igor,
A registry component, from a 32-bit package, that is marked as "64-bit component" will be installed both, on a 32-bit system and on a 64-bit system, in its corresponding location. Although this scenario violate
ICE80 Windows Installer validation rule, until now no problems were encountered.
If you want to mark as "64-bit component" more components at once you should proceed as follows:
-if your components name contain a common label you can performed a search from the top right corner edit box
-the search results will be displayed on the
Search Pane
-in the Search Pane you should select all components, from the context menu choose "Properties" option and then enable the "64-bit component" option
-if your components name doesn't contain a common label then you can manually add them on the Search Pane by selecting them and pressing F4 shortcut key
-after you add the desired components in the Search Pane you should select all components, from the context menu choose "Properties" option and then enable the "64-bit component" option
Regards,
Daniel
