QWORD registry values

Using Installshield 2022 R2.

Is it possible to set a REG_QWORD value under a registry key? When using the "Installation Designer" they don't get displayed when looking at the "Source computer" registry so it looks like they are unsupported.

Hi - 

Its my understanding that Windows Installer does not support QWORD values in the registry table - hence why they are not displayed in Installshield.

We have a knowledge base article discussing this here:

In addition Microsoft's registry table details are here: 

I think the only solution here would be to create a custom action to create the QWORD entries.
(Be sure to add an uninstall custom action as well to clean them up).

Thanks for the info. I have done a custom action as a work around.

I am surprised there is still no support for QWORDS if they were added to Windows 2000.
