I cannot comment bc of missing reputation, but regarding Mark Redman's Solution - If you wonder you cannot find your key in the given path, checkout the WOW6432Node

From AdvancedInstaller:

"The Wow6432Node registry entry indicates that you are running a 64-bit Windows version.

The operating system uses this key to display a separate view of HKEY_LOCAL_MACHINE\SOFTWARE for 32-bit applications that run on 64-bit Windows versions. When a 32-bit application writes or reads a value under the HKEY_LOCAL_MACHINE\SOFTWARE\\ subkey, the application reads from the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\\ subkey.

A registry reflector copies certain values between the 32-bit and 64-bit registry views (mainly for COM registration) and resolves any conflicts using a "last-writer-wins" approach."
