According to End User License Agreement(EULA) you can install a product on 2 computers and use them, unless you are not working on them at the same time. However, though the product can be installed on two computers, only you need to use the product, renting or leasing to others is against EULA.

More clearly, here it is:
The Adobe product license agreement allows the primary user to install the product on a primary computer and also on a home or laptop computer for his or her use, provided that the two copies are not used simultaneously. While the activation process supports installing and activating Adobe software on two machines, the usage of the product on the second computer is restricted to the user who licensed the software. Allowing others to use a second copy of the software violates the product license agreement.
