i like to install dotnet frame work 4.0 for which i got this msg.:
Make sure that your computer has the latest Windows service pack and critical updates. To find security updates, visit Windows Update. If you are installing on XP 64 bit or Windows 2003 you might need to install the Windows Imaging Component. The Windows Imaging Component 32 bit can be found here . The Windows Imaging Component 64 bit can be found here .
my question is:
how to know whether i required 64bit or 32bit ?
and also, how to know whether i required windows imaging component or not ?
hope if i install dotnet frame work 4.0 - my existing asp.net3.5 projects wont get affected.
