small problem with DotNET.nsh
I think you know this script
# DotNET version checking macro.

# Downloads and runs the Microsoft .NET Framework version 2.0 Redistributable and runs it if the user does not have the correct version.
# To use, call the macro with a string:
# !insertmacro CheckDotNET "2"
# !insertmacro CheckDotNET "2.0.9"
# (Version 2.0.9 is less than version 2.0.10.)
# All register variables are saved and restored by CheckDotNet

The problem is:
I've got a message when my dotNET is older when required
"Your .NET Framework version: .
Required version: 2 or greater"
So why "Your .NET Framework version: . " is empty?
Where is an error?
I whant to show my current version of .NET
For example "Your .NET Framework version: 1.1"
And if I have not got .NET at all, I want to show
"Your .NET Framework version: NOT FOUND " for example
