>First, thanks Nir, Tom and Tobias for the inputs and suggestions...you got my brain looking at different concepts and I really appreciate it.
>
>I have taken all your input and have done some new experimenting (I "was" running out of ideas) and have narrowed it down to the fact that the conditional logic I am using is flawed (shocker! 😊).  
>
>I ended up on this page: https://www.firegiant.com/wix/tutorial/com-expression-syntax-miscellanea/expression-syntax/
>From the text on that page:
>	PROPERTY This will evaluate to true if the property has been set and has any value, even if this value is false or 0.
>	NOT PROPERTY This will evaluate to true if the property has not been set at all.
>
>Therefore, I have modified the customaction dll to either create a private property named DriverCondition if it is W10 or not create a private property named DriverCondition when it is not W10.
>
>Then, the conditions on the two Components look like:
> 	<![CDATA[NOT DriverCondition]]> <==This is not a W10 computer
> 	<![CDATA[DriverCondition]]> <==This is a W10 computer
>
>But, ideally, I would like to do a comparison of the private property's value (DriverCondition) to a value (preparing for other curve balls that MS comes up with).
>The current approach above is really just a boolean (2 states).
>What I would really like is:
>If (DriverCondition == 0) <== OS less than W10
>If (DriverCondition == 1) <== OS is W10
>if (DriverCondition == 2) <== This is the next Windows OS after 10 😊
>How do you do this with a property and does anyone know where this documentation resides?
>The comparison logic seems really sensitive 
>
>Some questions in my head are:
>For the comparison constant, do you put no quotes, single quotes, double quotes, what if it is a numeric?, is everything treated like a string? Can you apply xslt transforms on it to make it numeric, etc.
>For the property, do you just reference the variable as x, $x, var.x, etc.?
>
>Thanks again for all the great help!

>@Anthony: ok... just read same guids for mutually excluding components.
>Assume this will in your case cause trouble with the wrong installed files
