Advertisements My computer came with Vista home premium. My Tivo is a series2. I am trying to download 2.5 desktop. I am at the installation window (for the 7th time). It says updating system, the software is being installed. The download bar is present but for the last 30 min. it hasn't showed activity the bar is blank. This is the same thing I have gotten each time I try to install. There are no error messages until I click cancel (installation). I then get a microsoft window that says, tivo install helper service process stopped working and was closed. A problem caused the application to stop working correctly. Windows will notify you if a solution is available. But that window may have appeared because I cancelled installation. I am downloading as administrator. I have installed with McAffe disabled, exact same scenario. I had 2.4 on here at one time and uninstaled that months ago. I have rechecked for files and have done the tivo unistal, same scenario. Have not seen this problem discussed in forums unless I missed it.
