sorry about the delay. a bit tired and busy lately.
this is a curious one. data.cab files are associated with InstallShield-based installations. itunes 7.0.x installers are not InstallShield-based, although earlier versions are. so it's choking on an odd file. (something perhaps that it's trying to uninstall from a previous installation.)
so perhaps let's get an itunes 7 installer log to someone who can interpret installer logs.
1. Open a command prompt window. (Start menu -> Run. Type in "cmd". Hit return.)
2. Drag and drop iTunesSetup.exe onto the window so that the full pathname of the file is at the command line prompt.
3. Type in a space, then the following line:
/l*v C:\log.txt
4. Hit return.
5. The installer will create a log file:
C:\log.txt
Find that file and
send it as an attachment to this email address.
in the email to Roy, be sure to include the following information:
- A link to the thread on Apple Discussions where the issue is being discussed
- The username you are using in the thread
- The version of iTunes you are using or trying to use
- the version of Windows you are using (mention service packs)
- A concise description of the issue you are seeing
- The exact text of the error message you are seeing
