I know there has to be someone that has done this as it seems like it could be a common problem.

Here are my needs:
I need MPLAB v7.20 and the C18 Compiler v2.40.
I need MPLAB v8.10 and the C18 Compiler v3.10.

How do I dual install both of these to work.

I'm trying to program VEX robots this week, so I have to use my v7.20 and v2.40 of MPLAB and C18.

I also need to program our FRC robot this week, and we use Kevin's code, and we need MPLAB v8.10 to open the file, and we have been using v3.10 of C18.

Another alternative would be to find VEX code compatible with MPLAB v8.10 and C18 v3.10.

I've tried to install both before, but as anyone can guess, it didn't do so well.

Any help or advice?
