Error 1603: A fatal error occurred during installation.
Other Messages:
Error 1603 is a generic error generated by the Microsoft Windows Installer (MSI). This error tends to be system-related, rather than linked to specific software.
Certain files on the machine are locked, or setup attempts to reboot because of this locked file which leads to a failure. To make sure that a locked file is not causing the error, do the following:
The system temp directory is not clean. This is the temp directory that setup extracts files to and runs from. Either the temp directory does not have enough available space, or it has too many files that may conflict with setup files.
Clean the default temp directory and free up hard-disk space by removing unneeded files.
Exit or turn off conflicting programs, including virus scanners, word processors, spreadsheets, web browsers. Then start the installation again.
