The first time I bought the Pro version after reading so many good reviews, I formatted my laptop just for the sake of having all my installations of my programs monitored with Revo Uninstaller and to ensure everything works perfect...I installed all the programs one at a time.... One day, there was an update for Java, so I uninstalled the current Java using Revo Uninstaller but when I launched Firefox all my bookmarks, settings, addons were gone! as if I had just installed Firefox.... I was very mad and contacted Revo and got a refund.....they didn't even argue with me or try to tell me that I did something wrong....seems they know their uninstaller has some issues..... anyway, a few months later, Revo Uninstaller was on a 50% discount......so I thought let me give it another chance because according to all reviews I read it seems to be the best.... This time I bought it......installed and activated.... then I had a small glitch with my laptop so I formatted and reinstalled Revo Uninstaller but it wouldn't activate!!! I contacted support and they reset my activation code although I told them I was not happy about it being so darn sensitive it's not like I formatted a 100 times or used it on another laptop......my laptops has the same computer name their app should be able to tell like all other programs which have an activation method.... Anyway.....they reset my code......but after a few days, when I launched Revo Uninstaller....it again told me it was an Unregistered Version! So much for being honest and paying for an app!! I have lost faith in this company and they issued me a refund yet again....at least they don't rip you off in that.... I have learned my lesson....I won't bother with these Uninstallers at it takes double the time to install apps while having them monitored and any small glitch or disk activity and you are asking for troubles..... Furthermore, Revo Uninstaller currently does not support installation of programs which require a reboot like Neto 11 for example..after Nero 11 installs a few components, it reboots then continues to install the rest.... Revo's take on this was that I need to create to monitoring logs and name them Nero (part 1) and Nero (part 2)...installation of programs which require a reboot will be supported in the next version of Revo Uninstaller but for now you have to do it manually and I still don't see how this would work when you want to uninstall that program and it has 2 logs.... just wanted to share my experience on this.... Ill never use an Uninstaller or registry cleaner anymore as they do more harm than good.
