I would say that this isn't the optimal way to do it. Since V2.0 isn't always backwards compatible with V1.1.
I now made an installer for an ASP .NET V1.1 solution. And I needed to be sure that V1.1 was installed. This is my solution for this problem:
Function CheckDotNet
StrCpy $0
ClearErrors
ReadRegStr $R0 HKLM 'SOFTWARE\Microsoft\ASP.NET\1.1.4322.0' 'Path'
IfErrors 0 +2
StrCpy $0 'not found'
Push $0
Exch $0
FunctionEnd
/T
- GetCORVersion is a defined API function provided by the .NET framework. There's no reason it'll not work with .NET 2.0. Reading from the registry is the undocumented method and your specific method relies on a very specific .NET version. --kichik 06:43, 19 July 2006 (PDT)

I think the issue here is in such a scenario:
The user has .NET framework 2.0 installed, but not .NET framework 1.1. But your program needs .NET framework 1.1. (Yes, I have seen computers installed like that)
The method would thus allow the program to be installed (as .NET framework 2.0 is detected), but yet it cannot be run (as your program needs framework 1.1).
i.e. each .NET framework version can only run programs built for that version (with some exceptions like services packs which are compatible with the no SP versions)
