He mentioned that when uninstalling a signed msi package you still get the&nbsp;scary this-package-is-unsigned dialog. Reason is that&nbsp;the&nbsp;installer&nbsp;tosses out files from the cab it doesn’t need to save space. Obviously this will ruin the hash value and invalidate the signature. </P> <P class=MsoNormal mce_keep="true">&nbsp;</P> <P class=MsoNormal>Maarten</P><img src="http://blogs.msdn.com/aggbug.aspx?PostID=850445" width="1" height="1">windows Vista Application Compatibilty XP port MSI sign certificate installer
