On Sunday March 8, I spent several hours on the phone with both TiVo and Digital River’s (TiVo’s online license key fulfillment provider) technical support teams. After installing the generic TiVo Desktop 2.7 software under the Windows 7 Beta , the desktop software would NOT accept my TiVo Desktop Plus License Key. It kept telling me I had an invalid key.
The only solution TiVo’s support team had in its database was to reinstall the app – which didn’t work when I tried it. Digital River issued me a new license key. The TiVo Desktop 2.7 app rejected that key as well.
After a couple hours and four phone calls we/they all gave up. I was about to try installing the older TiVo Desktop version 2.6.2 when it occurred to me to try running BOTH the installer and the app in Windows Vista compatibility mode.
VOILA!!!! That worked!
TiVo Desktop 2.7 accepted my Desktop Plus License Key and the application has been working fine under Windows 7 beta ever since.
