I installed the trial version of X2 yesterday... I guess it's some reduced version of Producer. I was really surprised by some of the elements of the install (Microsoft Visual C++ 2010 redistributables) and how this might mess up my machine when I uninstall it for the purchased version. Or maybe you just buy a key and keep the current install? But in my case I don't need the Producer version. I have some compiler software on my machine already, Embarcadero Rad Studio 2010, Visual Studio 2008, etc. and I' really worried that the uninstall is going to mess up my machine. Is this the correct procedure... uninstall the X2 Trial Producer and then buy/install Essential or Studio? I should have backed my machine up right before that install!

i think your worry about nothing grant , im sure when the trial runs out , you buy the key to enter. uninstall should not do any harm either

No problems unless your development environment tries to call the new libraries, but they are named differently and have different headers. 
 
On the other note, I would uninstall the trial version before installing a licensed copy of a different product.  Both can and will cohabit on your system, but you don't need the clutter.

Yes, remove the trial version first.

In the past (even now on one of my backup stations) I've been able to run multiple versions of Visual Studio at the same time so I believe the libraries and such are 'compartmentalized' these days. IOW: the C++ runtime shouldn't be an issue.
