I would try the following...

1: Uninstall TL completely. Let unistall-shield (or whatever comes up when you uninstall) uninstall TL. Then manually delete the TL folder. (To avoid any re-install conflicts later on.)

2. Examine the Windows Temp folder and empty it completely. (Sometimes stuff in that folder interfers with installations.)

3. Turn off any anti-virus programs you have. (They are reknowned for interfering with installs.)

4. Re-install TL. (If you are using the online method instead of downloading the whole file, then leave your anti-virus off while you install.)

5. Reboot.

If that doesn't work... that is, you get the same error message. Copy the dataobj.dll file into the Windows Systems folder - provided there is not one already there. If there is already one there, do not copy it across.

Let us know how it goes by trying the five points above.
