Why do I have to reinstall InDesign CS5.5 at every start-up?

Question

I've had InDesign CS5.5 only a few days and have had to reinstall it everyday. It installed fine from the disk the first time. I used it for a couple hours, ran perfectly. I turned off my laptop that night and the next morning when I went to use InDesign again I received the following error message and was unable to access the software:
Adobe InDesign is missing required files. Please reinstall.
Missing files: \Program Files\Common Files\Adobe\Type Support\...\CP1252.TXT
Each time I have reinstalled and once again the program works fine. Until I turn off my laptop. I thought an old trial of InDesign might be part of the issue but I've uninstalled all that and still have the same problem.

Thanks in advance for any help.

There have been two similar reports in the last year or so that I can find, and it looks like an installer problem when CS3 was previously installed (did you have CS3 or CS4 installed and remove it?).
What seems to be happening is that the type support files aren't properly written to the correct location, and it wasn't entirely clear to me this morning if either previous report was finally resolved. That said, I'd do the following:
Uninstall using Windows control panel.
Reboot
Run the CS5 clean tool: Resolve installation problems with CS5 Cleaner Tool
Run MSconfig and trun off non-essential startups, especially antivirus, browser helpers and toolbars, iTunes, and instant messengers.
Reinstall any versions you want, in chronological order. Be sure InDesign is installed into the Program Files (x86) folder (this should happen automatically if you leave the default location).
Run MSconfig again and restore normal startup.
