What is the patch for? Smaller patches that aren't needed for everyone, ie a specific driver patch, don't come with a .exe file. The individual files are loose inside of the .zip file and you need to copy them to the folder that it shows in the .zip file. As you can see in the attached picture, this patch has two different folders that need to be updated. All the files under outputdrivers need to be copied into the outputdriver folder of flexi. The program folder contains both files and folders, see second image, you can only copy the files. Don't copy the folders as this could delete all of the other files within these folders. You just keep on copying the individual files into their appropriate folders. Once this is done I typically clear preferences in Flexi to be on the safe side bu this will depends on what the patch is for.
