Is it possible to run the program on two computers and that they will sync between each other?

There is no 'sync' option but if you copy the project folder to the other computer then it should work.

Or can use Google Drive, One Drive, etc to store the project and it will be available from any of your PCs

This is what I do.

I have a shared Synology drive which I can access from anywhere (like Dropbox etc. but the data is stored in my house).

Each shared area automatically maps to something like D:\cloudstation\mydrive on my desktop and c:\cloudstation\mydrive on my laptop (I've got a data disk on my desktop). Any data that I add/delete/change in either of those tow areas is automatically synched to the server and the other PC as long as I have a network connection.

So, to make them appear the same, I use the SUBST command to map a drive letter to the above two areas. So, for desktop, the command is
"SUBST X: D:\cloudstation\mydrive"

For my laptop, the command is:
"SUBST X: C:\cloudstation\mydrive"

As long as I use the X: drive for all my working, I don't have to remember whether I'm on a laptop or a desktop. It just works. It should work with Dropbox and other s/w which has local and server data and automatic synching.

I hope this gives you some idea of what can be achieved.
