Logitech Webcam Drivers System Administrators Guide CD Install Completion Behavior In case of double clicking Setup.exe, success or failure of the software Installer is reported by alerts which appear to indicate various errors, or upon reaching a "Congratulations" screen at the end of the install. In the case of a silent install success and failure must be determined by return codes, or by looking in the applications events log maintained by the operating system. Special Consideration NOTE: If an error occurs in the MSI portion of the install then a meaningful return code is not generally passed back to the Setup.exe program. To verify that installation was successful, or to determine what error if any occurred it is necessary to examine the Windows Event Log for the system onto which the software installation was attempted. Web Install The web install is invoked by executing the program named "webreleasefull.exe", for installing onto a target system. When this program is executed the payload it contains expands into a media file set into a folder named "LWS_vv.v.v "(where vv.v.v is major, minor and release version numbers), in a temporary file location, and then executes the program Setup.exe in that folder. The Web Install differs from the CD Install as follows:  The payload expands to a temporary location before installing. The temporary location used is the concatenation of the standard Windows temp file path (usually c:\Documents and Settings\username\Local Settings\Temp). In order for a successful web install, there must be write access and sufficient disk space to expand and write the Setup items. Completion Behavior The web install executable does not provide a meaningful return code. As with a silent install using the CD media, the termination of the "front-end UI" setup.exe indicates the completion of the installation process and the system event log can be examined to determine success or failure. Upgrading Special Consideration -- When upgrading from and earlier version of the software, using an installer residing on a network drive it is recommended that the earlier version of the software be uninstalled before installing the newer version. pg. 5
