February 28th, 2007· There is no practical limit on the length of the optional command issued by self-extracting Zip files after the unzip operation completes.
· You can create self-extracting Zip files that both unzip and overwrite automatically.
· Self-extracting Zip files no longer contain the "licensed to username" text, and copyright information is in the "About" box only.
· A dot as the "Unzip To" folder unzips to the current directory instead of the directory containing the self-extractor.
· Empty directories in the Zip file are created during the extraction process.
· The programs and files for WinZip Self-Extractor have been changed to reflect the new company name, WinZip Computing, Inc.
· Uninstalling WinZip Self-Extractor now displays a message indicating the uninstall has completed.
· Uninstalling WinZip Self-Extractor now removes the "Version" key information from the Windows registry.
· Attempting to start WinZip Self-Extractor when another instance is running will now display a message that WinZip Self-Extractor is busy and to try again later.
· The creation of 16-bit and MS-DOS self-extracting Zip files is no longer supported and Windows 95, 98, NT 4.0, 2000 or Me is required to create self-extracting Zip files.
· The help dialog displayed when WinZip Self-Extractor is run using the /? command line option now includes updated information on the wzipse32.exe command line options.
· A problem running some commands that used quotes or ".." folder references has been corrected.
· The "Ready to Create" panel in the Wizard for self-extracting Zip files for Software Installation now displays the location of the selected icon, if one is selected.
· When running with Internet Explorer installed but Windows Desktop Update (Active Desktop) not installed, if the self-extracting Zip file executes a command after unzipping, the self-extracting Zip file did not close properly and couldn't be deleted immediately. All files were extracted correctly, and the command was executed correctly. The self-extracting Zip file could be deleted after a system restart or after a short period of time had elapsed. This has been corrected.
· The text in the "About" box can be modified for both standard self-extractors and self-extractors for software installation (in earlier versions, the About box text could only be modified for self-extractors for software installation).

· WinZip Self-Extractor can be run from the "Start" menu's "Run" dialog box by simply typing "wzipse32" (in earlier versions, you had to type the full path, for example, "c:program filesWinZip Self-Extractorwzipse32").
