Newbe Relevance Question

I’ve had BigFix for a while now, but have just started digging into the relevance language. I’m sure I’ll get better as time goes on, but for now, can someone tell me if the following makes sense?

Basically, I want a task to be applicable to only XP and Win7 machines. If it’s an XP machine, I want it to also check to make sure that .NET 1.1 is installed by looking at a registry key and finally regardless of OS, I want it to check to see if a particular app is installed by looking at another registry key (TheDotNetFactory). I have the following relevance and so far it looks like the correct machines are reporting as relevant, but I wanted to double check with the experts!

(name of operating system as lowercase = “winxp” and (exists key “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\Policy\v1.1” of registry) OR name of operating system as lowercase = “win7”) and (NOT exists key “HKEY_LOCAL_MACHINE\SOFTWARE\TheDotNetFactory” of registry)

Thanks for your time.

I’m not an expert (“but I play one on TV” har har). I would suggest using parenthesis to indicate the order of precedence, rather than relay on the AND and the OR to be read in the right order. Therefore I would make it look like this:

(((name of operating system as lowercase = “winxp”) and (exists key “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\Policy\v1.1” of registry)) OR name of operating system as lowercase = “win7”) and (NOT exists key “HKEY_LOCAL_MACHINE\SOFTWARE\TheDotNetFactory” of registry)

That may be overkill with the ()'s, but better safe than sorry.
