Recommended Process for Computers with an Evaluation copy of ArcGIS
The work around
is a protocol for this as follows - assuming that this error has NOT
yet occurred due to system clock setback prior to moving from an evaluation
to a full version of ArcGIS9.
If it has
occurred, then a full system rebuild will be required starting with the
manufacturer's original restore software or MS operating systems if build
1. Backup any
GIS non ESRI data or projects that you have stored in the C:\ESRI or
C:\Program Files\ArcGIS or C:\Program Files\ESRI locations. I always
recommend NOT storing new data in these locations anyway, but creation of a
"gisdata" folder and "gisproject" folders outside of
these program folders always to avoid just this issue if the program is ever
uninstalled or reinstalled and overwritten. These two folders "gisdata"
folder and "gisproject" folders should be on your data portion of
your partioned hard drive to avoid data loss if a format is ever needed to
be done of the program drive portion.
2. Before installing a permanent ArcGIS
license on any machine which has had a working evaluation copy of ArcGIS9
installed, one must fully remove the ArcGIS9 evaluation copy using the
proper WinXP control panel add/remove program process. Also to be safe,
fully remove your ArcView 3.2 program if also installed.
3. Reboot the
machine after the uninstalls.
only - Check the registry using regedit to ensure no ESRI or ArcView
entries are present. In test units, both ArcGIS9 eval and ArcView 3.2
had been uninstalled, yet there did not appear to be any remaining registry
entries on the test units after proper uninstall on units which had NOT
experienced this error occurrence.
ArcGIS 9 full version and the permanent license. Reboot the machine.
ArcView, as desired. Reboot the machine.
Technician Briefing Point:
If this error
"The system clock has been set back to the past. This is not
allowed". is reported by a user when attempting to run ArcGIS,
then it is due to a system clock reset which DeepFreeze will correct or a
manual reset of the system clock to the correct time again.
building an image, ensure that no evaluation copy of ArcGIS is installed. If
so, then select a unit which has not had it installed just to be safe. Do
the normal ArcGIS install and permanent license set up for the image. This
should avoid this error situation from being more than a nuisance factor if
students reset the clock.
