This is a simple tool for registering ActiveX dll and ocx controls. It uses a Windows interface so it is quicker and easier than working at the command prompt. To use this utility, unzip the file and run the executable. In Windows Vista you must run as the administrator. Click the "Browse" and navigate to, and select, the DLL or OCX file that you wish to register. Then click the Register button. Files can also be unregistered by using the other button. In the case of ASP components which are used by IIS, you must make sure that the Internet Guest User has read and execute permission on the DLL file, or the directory containing the DLLs, otherwise an ASP 0178 error will result. It is not usually necessary to reboot the computer after registration, but occasionally this is required. If you register an ASP component and receive an ASP 0177 error, check that you have typed the class name correctly in the script and if it is correct and you still get the error, try rebooting the machine.
