Hello, i have probably the same problem. I downloaded the 2 files rotorzconnect86.zip and rotorzconnect.exe. When i run the setup in the archive rotorzconnect86.zip i get the message: "Setup cannot continue because some system files are out of date on your system. Click OK if you would like setup to update these files for you now. You will need to restart Windows before you can run setup again. Click cancel to exit setup without updating system files." I clicked OK and another message appears, i clicked again on OK and my system reboots. When rebooted i run setup.exe again, but the same message appears :( I have deactivated my firewall before i have executed setup.exe. I am running Windows 2000. Can anybody help? Best Regards Lotion
