I'm slowly being tempted to move away from VS 2012 to VS 2013 Community Edition but don't want to do so if it implies uninstalling VS 2012 Express as I'd want to be sure that all my past projects compile fine with it.
Are there any conflicts between both versions or can you safely install the newer version into its own folder?
Is it even necessary to be afraid that some projects wouldn't compile without involved setting modifications, paths etc?
EDIT:
Sorry don't bother, I finally found the clear & concise answer that I was looking for.
If only the legalese could do the same :p
Q: Can you install Visual Studio Community 2013 and Visual Studio Express editions on the same machine?
A: Yes.
