Article #25363: Isc_license.dat can't be validated or read

Problem:
Getting error "isc_license can't be validated or read" when installing 
InterBase 4.2 or when starting ib license manager.

Solution:
Licensing for 5.0 is different from 4.2 and they are not compatable 
with each other.  Check the following:

*  gds32.dll file is for WI-V4.2.1 and not for WI-V5.0.0

Starting with InterBase version WI-V4.1 the gds32.dll file contains 
version info to determine the version being used.  Alternately the 
time of day that the file was created will also indicate the version.  
For example, a creation time of 4:21am indicates the version is 
WI-V4.2.1, while a creation time of 5:00 am indicates the version 
is WI-V5.0.0.

*  ib_license is a 4.2 license file not a 5.0 license file.
