Will installing Visual Studio 2013 Preview mess up 2012?

Question

I’m currently developing with Visual Studio 2012, and I was wondering – would my environment be messed up by installing the Visual Studio 2013 Preview?

Answer 1

The known issues for Visual Studio 2013 Preview imply that installing it is safe. One of the issues is “The remaining Visual Studio application is broken after you uninstall Visual Studio 2013 Preview or Visual Studio 2012”:

Symptoms

Consider the following scenario:

[basically, you have installed VS 2013 Preview]

In this scenario, when you uninstall Visual Studio 2012 or Visual Studio 2013 Preview, the application that was not uninstalled is broken.

Workaround

To work around this issue, repair the Visual Studio application that remains on your computer.

It says that an application is broken when you uninstall the other one. That implies that before that, when they were both installed, they were unbroken and working fine.

That issue itself is nothing to worry about, as long as you remember to repair your remaining Visual Studio application after uninstalling another.
