I always close my web browsers before I run a cleaner. I am not sure about Adobe being ticked. What is the default? I know that not doing so compromises the clean. I run Windows 7. I have the version 13 of Firefox and the 3.21.1767 version of CCleaner.
What does the bit version of my PC have to do with it? I am running 64 bit. For my understanding please explain the difference it could make?
Your second suggestion is quite likely the solution. I have been upgrading Firefox from within a pop up that I see. i have never uninstalled then done a clean install.
Clicking the pop up is just so much easier? Hmm, the laptop I was using I was returning to a friend and was not specifically sensitive. I was just flagging this for the benefit of the community, really.
It is a shame there is no easier way than what you have suggested as I can imagine fewer people would take the time to do this.
