Hello de nicola:
I have an entire page devoted just to the Palm Z22, listed below.
Many people report issues with trying to connect the Palm Z22 to new 64 BIT Operating systems like Windows 7 and Windows 8, and although somewhat obscure and time-consuming to set up, this can be done. ONE known software company has a 64 BIT driver, which, when used with other software, can get the SYNC functions working again. Another method is to put a VIRTUAL Windows XP on the Windows 64 BIT Systems, and then SYNC using the already working WIndows XP to get the data from files on the "new" 64 Bit Systems, and back...
I also deal with battery problems, touch screen problems, maintenance, repair, and upkeep issues, so that you may find the page of value! It is at:
I hope this gets your Palm Z22 up and running again, and keeps it that way...
