OFF97: Admin Setup Reports Not Enough Free Space

MORE INFORMATION

When you run the Microsoft Office 97 Setup from a machine running Windows NT, the mechanism in the Setup program that calculates free disk drive space "wraps" at every 4 GB. So, if the disk to which you are installing Microsoft Office 97 contains more than 4 GB of free space, the Setup program incorrectly reports the amount of free space and may even warn you that there is not enough free space available.

For example:

                      Free Space
   Actual             Calculated        Amount of Free Space
   Free Space         By Setup          Ignored by Setup
   --------------------------------------------------------------------
   500 MB             500 MB             n/a
   2700 MB (2.7 GB)   2700 MB (2.7 GB)   n/a
   4200 MB (4.2 GB)   200 MB             4000 MB (4 GB)
   6700 MB (6.7 GB)   2700 MB (2.7 GB)   4000 MB (4 GB)
   8100 MB (8.1 GB)   100 MB             8000 MB (8 GB) (two intervals)
				

If the hard disk to which you are installing has between 4 and 4.5 GB free, or between 8 and 8.5 GB free, you may receive an error message stating that not enough space is available. If you are sure that enough space actually is available, click "Install Now" to override the disk space warning.

Note, this error does not occur when you perform an administrative installation from a computer running Windows 95. However, in Windows 95, the Setup program indicates that a maximum of 2 GB of free space is available, even if the true amount of free space is higher.
