Accessing files from installation archives

Some installation archives do not allow to extract files manually by renaming them to .zip, .msi or .cab. In order to get the files the archive contains, start the setup and continue until you get the error message telling you that your OS is not support. Do not click OK/Cancel at this time. Leave the setup running and open an explorer window to C:\Documents and Settings\Username\Local Settings\Temp\. Switch to details view and sort descending by Date of creation. One of the directories which were created 1 minute ago should contain the extracted files of the installation.
