uninstall current .net 2.0 and .net 4.0 installations, reinstall .net 2.0, make sure to choose the right environment (32/64 bit).
then install .net 3.5 full package.

What O/S are we dealing with here? .net 3.5 uses the .net 2.0 CLR, .net 4.0 is a total rewrite and uses the .net 4.0 clr

vista/Server2008 and higher have .net 3.5 as part of the o/s

you send me more than one thing, that is a Windows 2003 R2 enterprise edition. that server can't go to the internet at all.


"uninstall current .net 2.0 and .net 4.0 installations, reinstall .net 2.0, make sure to choose the right environment (32/64 bit).
then install .net 3.5 full package. "

will the uninstlal of current .net 2.0 and .net 4.0 require the boot ?

what is the sequence of uninstall and install ?

just uninstall all of them and then just install .net framework 3.5 is ok  ?

the litespeed backup tools I am using just like .net 3.0 or 3.5 .
*** Hopeleonie ***IT ManagerCommented:
You can download the Tools and take it to the Server... Both Tools will work on Windows 2003 R2 enterprise edition.
marrowyungSenior Technical architecture (Data)Author Commented:
if that server can't be restart, is it impossible to uninstall both ?

that installer 5.0 do not have redistribution package at this moment, right?

or where to download it?

1) do any previous .net framework needs to be install before installing it?
2) need to reboot after installing it?
David Johnson, CD, MVPOwnerCommented:
It is now part of the Windows SDK for Windows 7.
marrowyungSenior Technical architecture (Data)Author Commented:
