Assuming you downloaded files to N800: - Go to the directory where you downloaded the zip file - run "unzip <downloaded_file>" - Now look for file(s) with .prc extension. Under PalmOS, .prc files are executables and .pdb files are data. - Start gvm. Click "Install". Browse to the directory where you unzipped the downloaded file. Select .prc or .pdb file (whichever one you want to install). Hope this helps.
