What I would recommend is boot to safe mode, uninstall the file and all its components. Then goto start -> run and type in regedit. That will bring up the registry editor. If you arent comfortable with it its ok. Do a search in the entire reg for "photoshop" or "CE2". Delete any reference to photoshop. Also, go into your Application Data folder. It should be located in:
C:\Documents and Settings\Administrator\Application Data
Or something. If you have an adobe folder go into it and delete any reference to photoshop or ce2. Unless there is a photoshop folder in teh data folder then just delete that. Restart once again in safe mode and then try to install it taht way. browse the CD and load the Setup.exe file, dont use the autorun. Ive came across some cases where the autorun isnt programmed right and screws installs up. Sometimes things are missing, etc... Try it and post your work. kthx.
