I used Returnil for a long time. I tried out the beta versions when you were first making it compatible with Vista 64 bit. I had to reinstall my OS a couple of time, but with some hard work on your part, I was so glad that you were able to create a version that worked with my Vista 64 bit desktops. I used it for a long time, many months, and it was so wonderful! Smooth as silk. Never a problem or issue. Then a few months ago, maybe as far back as a year, I started having problems again. Blue screens, applications slowing down, and computer freezes. Just like it was with the first 64 bit beta versions. Finally, I had to uninstall it on my 2 desktops. Never had any problems on my Windows 7 or Vista 32 laptops though. A few months ago after a long break from Returnil, and after a clean reinstall, I decided to give the newest version a try, hoping that maybe it would once again work. I wanted to make sure that there was no incompatibility with an antivirus or firewall, so I decided that since Returnil has an antivirus and windows has it's own firewall, that I would try Returnil again without them. Right way, I started having the same problems that I had with the first 64 bit compatible Beta versions of Returnil. I would click on an icon, my browser icon, and it would not respond. I would have to click it again and it would take a long time. It was like my computer was sick or something. It just didn't run properly. So I uninstalled it and everything was back to normal immediately. I then did some google searches for some earlier versions and was lucky enough to find a couple of them. I have a Returnil 2010 version installed right now. No problems. It runs just fine. But I don't know if this version has been patched to protect me against any newer root kits or any other new types of malware that may be able to bypass earlier versions. I am wondering if adding the extra features over time has made Returnil incompatible with Vista 64 bit? And I have noticed a few posts here and there of people requesting a cleaner, simpler, more basic version of Returnil. I am hoping that this is something that you will consider offering. I don't want or need any extra features. I just need the virtual mode and maybe the antivirus. I truly hope that you will consider this because I can no longer use current versions of Returnil on my Vista 64 bit desktops. And I really hate that. I just hate it. However, I can still use a 2010 version that I have installed. The rvsgui in my program files says 3.1.8774.5254. This is what I have installed right now. When I mouse over 2 other setup files that I have saved, I get these numbers: 3.1.7662.5174 and 3.1.7662.5254. So I assume that the 3.1.8774.5254 version that I have installed is the most recent of the three 2010 versions. Is this correct? I also have a setup file for this version, 3.2.10743.5462. Can you tell me how old this one is? I would like to use the most recent one that still works. I have a newer version on my Vista 32 bit laptop and it works just fine. I do have 2 messages from Returnil advising me that there are newer versions, but I am afraid to update to newer versions because I do not have the setup file for the version that is now installed on that laptop. Another question. If I bought a copy of Windows 7 and installed it on my desktop, do you think that this would solve my problem and enable me to use the current version? Anyway, I hope you will consider offerring a basic version of Returnil. I would gladly pay for a clean bare bones version of Returnil that works with Vista 64 bit..... with just the virtual mode and antivirus.
