With a single Acrobat Pro XI license, how many computers can download the software?

The license allows YOU to install on two of YOUR computers for use by YOU. I emphasise the you, because the software must not be shared - that is, this cannot be used to get the software so that two different people can use it on their computers. Think of it as "my laptop and my desktop".

Hi,

It can be used on two systems but both the systems should be of same platform it the license is for windows then t=both systems should be windows if Mac then both systems should be Mac
