Answer 1

Installscipt: Where is your value located? Have you accounted for the 64- versus 32 bit sections of the registry?

• HKEY_LOCAL_MACHINE\SOFTWARE

• HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node

Perhaps investigate the 64-bit option here (REGDB_OPTION_WOW64_64KEY) if you need the 64-bit section of the registry.

AppSearch: for a simple registry retrieval like this, you could use AppSearch instead (System Search View). I don't have the time to make a sample for that right now. You can also see the System Search View / Wizard.
