Hi,
Before installing a software, I would like to check whether two GUIDs are available or not. If unavailable I would like to install otherwise no.
I have come up with this relevance:
(not exists keys "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{0D2426EF-A4D1-403B-B78B-2897D6AD3021}" of (x64 registries; x32 registries)) AND (not exists keys "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{0E8670B8-3965-4930-ADA6-570348B67153}" of (x64 registries; x32 registries))
Is there any other better way of writing relevance?
Thanks in Advance.
