These files are either zipped or self extracting. If you download a zipped file you will need Winzip to unzip them... Download the latest version from www.winzip.com.. or from the top of this page!!!!! Save the "filename".zip or "filename".exe file to a temporary folder. If they have a setup.exe file then you just have to follow the instructions on the screen. Make sure you are not in your Halsoft/VP Program when installing these files. Some files have a .txt file included which includes setup instructions and other "Important Information!!!!) All files were virus scanned prior to uploading and were verified as being clean. (If a serial number is included, which it will be if required... only use it if you have a registered version and have lost the number or if you are using it for educational purposes).
