Barbara, If you're upgrading from SR1 to SR2, just run the SR2 installer. You don't have to uninstall anything, and SR2 will replace SR1. I've done this upgrade, so I know it will work as I've described it.

If I install SP2, I expect to see both SP1 and SP2 in the control panel. I assume this is OK and I should not uninstall SP1. I have understood from other communications that the downloads are full downloads and not just an update. I just want to install what I should and delete any old software which should be gotten rid of. I have Windows 7 64 bit installed on my computer. Thanks in advance for any help. Barbara
