Desktop Version - Multiple Laptops

I have two laptops. I have downloaded Manager on both laptops, but cant seeem to access Manager on second laptop. Is this allowed?

Assuming you are referring to the desktop edition, yes, you can install it on as many machines at once as you like. But each will, by default, be accessing a different data file. Changes entered on one machine will not be reflected in the data file on the other.

If you want access to the same data file from both machines, you must move the data file to some remote storage location accessible by both. See this Guide: https://guides.manager.io/10348.

You need to be very careful, however. Both machines must always have the same version of Manager installed. And only one person at a time should access the accounting file.
