I also have the "Cordless Optical Freedom" combo and I've got the same problems. iTouch installs alright, but immediately closes and when you drag your mouse over the tray icon it disappears. I have however, discovered a way to install the newest version of Mouseware. In an email I just sent to Andy: "I know a whole lot of people use Logitech mice and keyboards (I use “Cordless Optical Freedom” and a simple “Optical Mouse” incase the batteries run out), and If you try to install the most recent version of MouseWare (9.76) you will get an error message similar to: “Our software can’t run on your system!”. Now this is irritating because it is an extremely useful tool for configuring your Logitech mice to work effectively in games and other applications. Well after being inspired by the article that explains how to install “Plus! For Windows XP” on Server 2003, I decided to go to work on the Logitech problem. I first tried the same command line approach which obviously wasn’t going to work due to the fact that the install is not a .msi file type, so I scraped that idea. What I did next was double clicked the install file, and waited while it unpacked and before closing the error message, I located the temporary folder it had created and copied all the setup files to another folder. I then went into the properties of Setup.exe and went into the compatibility mode tab and ran the setup in “Windows XP” compatibility mode. And guess what? The software saw my OS as windows XP and then successfully installed. I thought that this method might be worth while to include on your guide but maybe provide the users with a .zip version of the setup files with instructions. (I can provide this if necessary)" Hope this helps you guys out, keeps your eyes open on the iTouch problem, I'm sure logitech will eventually release new software.
