When you say "downloaded", this states that you obtained the installation program from the MTU.com web site using your download link.

Once you downloaded, did you locate the hoster2124setup.exe file and double click it? Normally this should not be on your Desktop as it is a setup/installation program that you use once, then store to a CDROM for backup safety, along with the download email you received with your download link, Registration Code and Registration Email.

Please tell us more what you have done so we can help.
