I currently program in in Qt4.6.2 on Windows 7 64-bit, and want to install 4.7 and also 4.8beta.... how do I Install all 3 and still be able to use all 3? will the environment paths identify which Qt version a particular application is? Or will only one path work for opening .pro files and/or executeable applications? So when I install 4.8 it runs just off of those .dll's and I'll have to physically put my 4.6.2 .dll's in the release folders of every 4.6.2 project? or 4.7 .dll's with 4.7 applications for that matter?.... I just want to be able to play with 4.8 while switching to 4.7, but still be able to use 4.6.2 for current in-progress projects.... and am worried that some of my other code uses depreciated classes from 4.6.2 and installing 4.7 & 4.8 will make these programs not work. I understand that installing them in different directories allows for multiple versions, but how does opening the SDK evironments and different .dll's work?
