compatibility issue

Hello everyone iam new to unity and me and my friend is working on a project on two different laptops.
My laptop is on 64 bit and his is on 32 bit. Can u guys tell me is this possible to run a 32 bit project on 64 bit or 64 bit project on 32 bit.
Sorry for dumb question...

 

If your project itself is 32bit, it will he fine on both machines. It doesn't matter if one of you has a 64bit machine or even using the Unity 5 64bit editor... It just matters that the project itself doesn't target 64bit if you want it to run on both machines.

 

We both created a project me on 64 bit and he on 32 bit but when we try to open my project on his laptop or his project on my laptop it won't run.. i mean is there any way to do that?
you can say half of work he is doing and half me.. so after fininsh the project we need to run both projects as one project

 

anyone?
