Hidden Registry Entries

[joshua.prettyman]

I've made quite a few commands recently and I'm looking to publish them throughout my company.  The idea would be to have them demand load, so I'm writing something to make the registry entries.  I'd like to look for the installed products then prompt the user for products that they would like to install to, but when I check the registry some products that aren't installed are showing up.

I should only have version 18.2 installed (according to RegEdit that's correct), but when I run the following query I find I have full fledged hidden entries for 18.1, and 18.0 as well.  Basically though, how do I check which versions are really installed?

RegistryKey key = Registry.LocalMachine;
key = key.OpenSubKey("Software\\Autodesk\\AutoCAD");
string[] str = key.GetSubKeyNames();
MessageBox.Show(string.Join("\n", str));

Look at some of the methods in the Application class.  Particularly Application.UserConfigurationManager.OpenGlobalSection() and Application.Version.

This is an installation program so it doesn't have access to the AutoCAD libraries... I was hoping to find something unique in the file structure or registry.
