Registry.DoesKeyExist

[calbert]

Why does Registry.DoesKeyExist() product a error line in the setup log when the key you are looking for does not exist. This seems to defeat the purpose of the function, which I think is to test whether the key exists so that it can be referenced without causing a error?

I don't see this. With this sample code

if not Registry.DoesKeyExist(HKEY_CURRENT_USER, "Something") then
   SetupData.WriteToLogFile("Info\tHKCU\\Something does not exist\r\n", true);
end
if not Registry.DoesKeyExist(HKEY_CURRENT_USER, "Something\\Anything") then
   SetupData.WriteToLogFile("Info\tHKCU\\Something\\Anything does not exist\r\n", true);
end
if not Registry.DoesKeyExist(HKEY_LOCAL_MACHINE, "Something") then
   SetupData.WriteToLogFile("Info\tHKLM\\Something does not exist\r\n", true);
end
if not Registry.DoesKeyExist(HKEY_LOCAL_MACHINE, "Something\\Anything") then
   SetupData.WriteToLogFile("Info\tHKLM\\Something\\Anything does not exist\r\n", true);
end

I get these results:

...
[10/29/2013 16:33:57] Notice	Start project event: On Startup
[10/29/2013 16:33:57] Info	HKCU\Something does not exist
[10/29/2013 16:33:57] Info	HKCU\Something\Anything does not exist
[10/29/2013 16:33:57] Info	HKLM\Something does not exist
[10/29/2013 16:33:57] Info	HKLM\Something\Anything does not exist
[10/29/2013 16:33:57] Success	Run project event: On Startup

Maybe you could post the actual code and error log - something else might be happening. Also, which version are you using?
