I downloaded the RIFT-Instal.exe file fine, and when I run the file it comes up with the Rift installer and starts to update and extract the files, but as soon as it's done, (as in 2 seconds later), it comes up with the "The installer has encountered an error and cannot continue [error #5167:80040154]. The create-shortcut fix does not work for me because it has no time to actually instal any files. When I do go into my program files, there is no Rift file. I set the path to Program files by default, so I am not changing the location of the files. If anyone has run into this problem and figured out how to fix it, please let me know ASAP. I am running windows XP.
