I'm trying to install PS4 hotfix PSE400W2K3014.msp and when it tries, either through IM or locally, it errors out on msiexec. All other MSI's will install but not this. I've reinstalled installer (latest 3.1 v2). the error in the event log is this: Event Type: Error Event Source: MsiInstaller Event Category: None Event ID: 1013 Date: 9/26/2005 Time: 3:05:41 PM User: UFPIAD\SA-Citrix Computer: GRCITRIX01 Description: Internal MSI error. Installer terminated prematurely. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. thanks ahead of time Jeff
