I've had TivoDesktop 2.8.3 for quite a while. (Windows 7) Today I purchased the code for the upgrade to Desktop Plus. However, when I go to help/purchase upgrade/and enter the code, I get the message, "The feature you are trying to use is on a network resource that is unavailable." ... "enter a path to a folder containing the installation package TiVoDesktop2.8.3.msi". I cannot find any file with that name. The installation package for 2.8.3 is TivoDesktop2.8.3.exe - NOT .msi I have re-downloaded Tivo Desktop and reinstalled to no avail. Now what? BTW - by default, it's looking for the .msi file in C:\Users\[username]\AppData\Local\Temp\ - I hope it doesn't expect anything in a TEMP folder to stay around forever!
