two versions of .net framework

i have two versions of .net framework installed in my pc somehow. I figured out this by reading KB318785 "How to determine which versions of the .NET Framework are installed and whether service packs have been applied" article.
i checked the mscorb.dll properties for version info. one is version 1.1 other one is version 2.0
a message in microsoft web site say Important: You cannot install two different language versions of the .NET Framework on the same machine
my question is: am i supposed to delete older version which is 1.1? if answer is yes then how to delete? thanks

 

Hi Halo, thanks for your explanation. I read again and you are right they are talking about two different languages.
Let me ask you then i need to upgrade for .net according to KB931212.
Can you verify for me please i am using XP service pack 2

for .net 1.1 i need to download
MS05-004 update which is NDP1.1sp1-KB886903-X86.exe ?

for .net 2.0 i need to download
this is very confusing for me because there are two updates MS06-033 and MS06-056

MS06-033 have 3 files to choose to download.
NDP20-KB917283-IA64.exe
NDP20-KB917283-X64.exe
NDP20-KB917283-X86.exe

MS06-056 have also 3 files to choose to download
NDP20-KB922770-IA64.exe
NDP20-KB922770-X64.exe
NDP20-KB922770-X86.exe

which ones i am suppose to download?
sorry for the long question. thanks
