Is Vista blocking the app at startup? You will have to set a task scheduler to get Riva Tuner to run in Vista. Make sure to write down the file path from msconfig. There is a "S" at the end of the file path that enables it to run silent (you dont see the program pop up).
The once and for all to fix that VISTA tray BLOCKED APP alert that is quite annoying in that you are alerted with every bootup that your app is blocked and you must allow the app to run each time by giving VISTA permission blessing. Boo on that. So here is the fix:
Remove the startup app that is offending by:
Start----Run----and type in msconfig.exe
Go to STARTUP Tab and remove the app that is blocked by Vista noting on a sheet of paper where the program is run from. If the program app is run from the startup menu, then just go to Start---All Program Files---Startup Folder and remove the app there.
