RClock10.exe is a self-extracting zip file that can automatically install RealClocks95 to the users hard drive.
No files are unzipped until the user is prompted.
When prompted it unzips a file to the users temporary directory. This filename is guaranteed to be unique. This file is then run giving the user a chance to try the software or install the software. If the user chooses to install they will be prompted for an installation directory. After the user chooses install or quits the temporary files are removed.
