Hello and welcome to Tom's Hardware Forums.
I'm not sure we can help - I worked on a 5732Z the other day and the only drivers available were for Vista and Windows 7. I found everything except the wireless adapter in the end. Go to the Acer website and input that model number then look for Vista 32 bit drivers - you might be lucky enough to get them to work.
If you have executable installation files, ignore those and point the Device Manager to the individual files below that .exe file.
