While trying to install MS Office 97 Pro on a new Windows XP box, I came across the following error message.

Setup couldn't create a SYSTEM.MDW file.  After Setup is completed, reboot your computer, then run the Workgroup Administrator before you run this application. (-1011)

Solution:

  1. Download and install MS Office 97 service release 1 (SR-1) for MS Office 97.
  2. Reboot
  3. Download and install MS Office 97 service release 2 (SR-2b) for MS Office 97.
  4. Reboot
  5. Run the Workgroup Administrator.
