For those of you who get the above error when right-clicking the OOo installer version 2.2.1 - latest (3.0 beta 2), I've found the cause: You have Zip Genius installed. Check out the following thread on the Zip Genius forums:Invalid size or check sum of file or unsupported compression format - Native error: 00008. File processing error, possibly disk is full. [Abort|Retry|Ignore]

In summary, Zip Genius scans every file that you right-click for compression and other info. Something about OOo's compression technique since version 2.2.1 is funky, causing Zip Genius to throw up this error when trying to decide whether to show you a Zip Genius item in the right-click context menu. I intend on cross-posting about this in the Zip Genius forums to see if they can't fix their decompression algorithms to be compatible with OOo installer files; however:
I would also like to state that perhaps the OOo team ought to consider the professional courtesy of revising their compression techniques for the Windows installer so as to improve compatibility with Windows archiving utilities.
