Paid ~ $750 for a PTC Prime Mathcad lincense - Where is my license file?

I was handed a 43 page PDF document and told to read this to get my license installed.  The PDF document makes no sense to me - it's all gibberish as far as I'm concerned.  My guess is that this document covers every license file case for every product that PTC owns.   Just so you know - I don't spend every day of a 365 day year installing licenses for PTC products.   I install my license once a year.  I'm just not going to remember how it works for my case.   It would be easier if I was handed the text license file.  That's what other companies do. 

Why Can't PTC just email me the license file and skip all the convoluted hoopla?  

So, how I'm I going to get my license file?  Please.
