Today I tried to download font idautomationhc39m. I find it on my desk top when I try to unzip (zipeg) error "failed to open archive........unsupported format I am using PC with Vista I have tried to open others always get the same message-

Can you tell me what I'm doing wrong?

why don't you just use the unzipper installed by default in windows ?
i have no problem downloading and unzipping idautomationhc39m

Click on the "Download" button, save the zip somewhere on your hard disk, go to the place where it is saved, double-click on the zip to open it, then either click on "Extraxt all files" or drag and drop the files elsewhere from the zip window (hold down the CTRL key to select several files at once)
