A NullReferenceException on any attempt to query in Linux (ubuntu x64 in my tests)
I was able to track this down to the following line in Constants.cs
public static readonly string OS_ARCH = GetEnvironmentVariable("PROCESSOR_ARCHITECTURE", "x86");
Sure enough, PROCESSOR_ARCHITECTURE is not set by default in ubuntu server x64 and when I set it, there is no failure.
I would fix this, but I'm not sure what this value is used for, so I am not sure what the appropriate behavior should be. Should we try to find the correct architecture here? And what is the correct string, "amd64", "x64", "x86_64"? Or do we really just want to know the value of that if it is actually not set, should we leave it blank? The issue is that the InfoWriter can't write a null, but it could write an empty string.
I'll submit a pull request if anyone can tell me what correct behavior should be.
