Cant install DT4

[Necrowizard]

Hi,

Im trying to install DT4, but it doesnt work.
it doesnt give any error or something, but it just shows the install screen, than i click next, and than it says i have to reboot, than after i rebooted, it shows the same screen again. and when i click next, it says i have to reboot again...


I already Reinstalled DT3.47, and uninstalled it, but it didnt helped.

What to do?

If you don't see an error message do you see a message prompting you to install SPTD with an OK and Cancel button?
