Can I move/copy 3ds Max install?

I'm trying to set up two copies of 3ds Max 2014 by copy pasting my install files to another location. The reason I want this is not very important, but basically I'm doing some experimenting and I don't want to ruin my original 3ds Max install. So I will be doing my experimenting on my second 3ds Max in another location.

I tried to install it again, but the installer won't allow it. I have copied it, but I get a MAXscrip error. http://i.imgur.com/5p6Oyjq.jpg

Does anyone know how to correct this error. Also the file path it is referring to is the install path of my original copy, the new path is C:\Autodesk\3ds Max. Is there a reason it is referring to the old path, if so is there a way to change it?

Lastly since it was referring to the original file path I tried to move the original install, this made the error stop, but I found that I could not open rendering settings on ether copy, so I assume that there would be similar problems.

So have anyone tried to change their 3ds Max install path, if so what did you have to do to get everything working.

Thank you for any help you can give me.
