From the FAQ:<p>&gt; 9. Can I use my personal license on multiple machines?<p>&gt; You may install the license on more than one machine but it may be used on only one machine at a time. To run multiple installations simultaneously, each instance requires a separate license.<p><a href="https:&#x2F;&#x2F;sales.jetbrains.com&#x2F;hc&#x2F;en-gb" rel="nofollow">https:&#x2F;&#x2F;sales.jetbrains.com&#x2F;hc&#x2F;en-gb</a> (#9 under License Types and Users)<p>Will I still be able to run multiple instances of ReSharper on the same machine? This is pretty essential to my workflow. For example, I have three instances of VS2015 open at the moment: One for my Unity project, another for a C# plugin, and a third for the installer. ReSharper runs fine in all of them.<p>I can also run these on my Windows machine while having IDEA open on my Mac. (Actually the Windows machine is a Parallels VM, but same difference.) Will this capability go away? That would be unfortunate.
