Never seen Windows 7 referred to as W7 before
was more to do with the 64bit as not all programs work in this environment.
yes they do, 64bit versions work in 64bit environments, the only difference is how the compatible cpu handles the data (more efficiently). Most 32bit programs will work with the exception of a few anti virus programs and a few hardware drivers.
W7 32bit is only able to see a max of 4Gb of physical memory (w7 home basic, W7 starter is just 2gb)- where as 64 bit is able to process up to 192Gb of physical memory on the W7 pro edition and upwards. But being an IT professional, you probably know that
If you take the time to look into what I'm saying you will find an install problem for Safari and possibly Firefox too because there is no self installer, yet you say it has an uninstaller?? If you are not interested then say so rather than trying to out do me in a pissing contest - I have nothing to prove to you are anyone else as my business is very successful which says it all!
Now not all 32bit apps working in a 64bit operating system. You didn't mention itunes for example? With this in mind I was simply asking if this toolbar will work in a 64 bit environment because your only ref was to XP 64bit which you say it's not compatible! So if XP 64bit is not compatible and there is no other ref to 64bit O/S it's no unreasonable to ask if it works in Win7 64bit is it??
