VI backwards compatibility with older run-time Engines

[Gormander]

I currently developed a VI in Labview 8.6.1.  I also created an exe for it so that I can run it on another computer.  However, the other computer has an older version of the Run-Time engine installed and so my program cannot be executed on that computer without upgrading the run-time engine to 8.6.1.  But....that computer also has some programs that run on that version of run-time engine.  I have two options here but I do not know the effects or how to do it.

1) Install a newer version of the run-time engine (8.6.1) - Will this break the current functionality of the programs already on it?

2) Is it possible to have my VI run on older versions of the run-time engine?  If so, how do I do that?

Thank you.

Installing a newer version of the runtime engine is your only option and it will not overwrite older version or have any affect on programs that use a different runtime.

As dennis said simply install the new runtime engine. We have machines that have 5 versions of the runtime engine on them and we haven't experienced any problems.

Thank you all.  I was hoping that it was ok since they give you options to include multiple run-time engines when you create an installer package.
