Bump - same question for an HP running Win7. I can't find it in Startup, the control panel uninstaller doesn't list it, and there seem to be no other ways to get to it. But it still shows up every time I boot up. I thought I was installing the VZW Manager for tethering when I installed it. Silly me...
I have the same issue with windows 7 and v cast manager. It doesn't appear in the add or remove. There is also no uninstall that I can find. It shows up in my system tray at startup but I cannot even locate it in the startup in msconfig.
I called Verizon twice and was told I would get a call back. After not hearing from them I called and they finally told me it is a windows problem. They didn't explain why they didn't simply call me back and tell me.
Of course windows says it Verizon's problem:
If you don't see the program listed and you want to uninstall the program, check the information that came with your program, or go to the manufacturer's website.
I would agree its a Verizon problem and would like to get it uninstalled. Apple is telling me to remove to troubleshoot a problem with my Verizon I phone.
