Types of Software Errors
There are a variety of types of errors related to operation of the software. If you get an
error message, it will probably refer to one of the following types of problems:
Type of Error
Description
Program Startup Errors
caused when you are trying to run a deactivated program.
Either the program has been recalled to the master disk, or
the activation files have been damaged.
Unauthorized Copy
Errors
caused when the disk being used for an installation or recall
is not a master disk, or has been damaged.
CTREE Errors
caused by an old or corrupt description database. These
errors are accompanied by instructions on what you should
do to correct the error. (Generally, try the
Repair/Compact
Data Base
option from the Utility Options menu.)
DOS Errors
caused when DOS cannot find a file or directory, use a disk
drive, or locate a printer. Often caused when a file is
missing from the hard disk, or when a printer or floppy disk
is not ready for use.
Not Authorized Errors
caused when the security system is active and the system
administrator has not granted you permission to use a
function, or the database is being used in a multiuser or
networked environment and another user has taken
read/write access (in which case you can only view the
program).
Exec Errors
caused when DOS cannot execute a file (the filename is
given in the error message). There are several reasons
DOS might not be able to execute a file:
•
the .EXE file may not exist in the program (usually
C:\SLC500\) subdirectory, or may be damaged. Run the
SETUP program and select the UPDATE option.
•
there may not be enough RAM available to load the
program. See the section on memory errors, later in this
appendix.
•
there may not be a file handle available to open the .EXE
file. Make sure the FILES=n line in the CONFIG.SYS file
is set to at least 40.
•
the temporary file directory specified in the Configure
Program Parameters screen may be invalid, or may
indicate a disk that does not have enough space.
