I would suggest to use the newest stable version, with is currently MSVC 2015. Then you need to update and adjust to changes look and feel less often. In general, installing two MSVC versions in parallel is no problem, the same is true for qt. The only thing you need to make sure is that none of these versions is listed in the PATH or other environment variables. Then you can use two build.bat files for the two versions, and set all needed environment variables (e.g. adding the qt bin dir to PATH for moc etc) separate in these two files. Furthermore, a new MSVC version requires a new dependency package. As I already wrote to David Hyde (who wants to compile LyX with a newer MSVC), I think that the current procedure of providing the binaries for a sepcific MSVC version produces too much work in the long run. Instead, a python or cmake script to download the sources of the dependencies and compile them should be written. This is more effort initially, but pays off in the long term, and also removes some pressure from you, since others can then create the dependencies they need without manual work for you. Georg
