How do I install both D2007 and D2010?

From what I have gathered, one can have both editions of Delphi installed. My concern is that default paths, etc, may get confused especially when installing 3rd party components.

The reason why I want to do this is I have some 3rd party components which have not been updated. Although I have the source files, I'm not knowledgeable enough to update them. I have tried compiling it for D2010 and received so many errors that it would be easier to install and use it in D2007.

I'm running Windows 7.

Thanks in advance.

Why not install them in two different VM's? – Jeroen Wiert Pluimers
Actually, that is what I did in the end. I had to reinstall my OS, and decided to install D2010 on the main OS and D6 in VirtualBox. – DoctorBean

The parallel installation of Delphi itself is no problem.

Regarding 3rd party components: Some of them (like JEDI) are able to recognize different installed Delphi versions and so you have no problem too. For all the other components I recommend to install them into different directories (and therefore use different Delphi library paths).

But if you have no Delphi 2009+ (Unicode) version of your library/component, you have to look for an updated version or update it yourself (, which may be complicated; there are many threads here on SO).
