Can we get a definitive answer on this popular issue? What needs to be done to distribute .NET SP2 in standard installs and patches?

In another thread, hrobinsonTX suggested a likely solution but I would really like to hear an endorsement from InstallShield or somebody who has tested it:

"C:\Program Files\InstallShield\Developer\Redist\0409\i386
has a file called dotnetredistSp1.exe which is identical to NDP10SP317396.EXE.

Do I ned to copy NDP10_SP_Q321884_En.exe and rename the copy as dotnetredistSp2.exe? "
