The problem that was originally reported yesterday (the inability to change the target folder during the installation) turned out to be fairly isolated.
We tested the installer on many different PC configurations and we were only able to reproduce the problem on one machine, but not others with the same specs and version of Windows.
So we’re going to keep working on it but for now you can go ahead and download your free Purchase Order Software, as the problem will only affect a very small number of machines, and even fewer customers, since not all need to change the default installation folder.
Again, sorry for any inconvenience.
