Welcome to the beta release of WinTek to install, you should unzip the zip-file with the -d option. Or, you create a directory called symbol in the directory where you want WinTek to live in. Copy all files with the extension "sym" to that directory. Copy the file bwcc.dll to your Windows/system directory if it not already lives there. Be carefull not to overwrite a newer version of that file... This program comes without any warranty! contact: krumm@geol.uni-erlangen.de apeterek@geol.uni-erlangen.de
