Question:
What should I do if I get an Access Violation?
Answer:
Access Violation errors are very rare and always related to the
individual computer on which they occur. They are not errors in
the ExpressMaintenance software but rather the result of something not
functioning right on the system that causes the program to lose its
place in memory. Usually an Access Violation results following
some other error and it is the preceding error that is of significance.
Again, Access
Violation errors are rare and always relate to the individual computer
operating software or settings. The exact cause of the error can
be difficult to find. Common causes typically are one one of the
following:
1. Corrupt or
insufficient version of Windows. See tech bulletin for
requirements - click here.
2.
Insufficient RAM memory or system requirements. See tech bulletin
for info - click
here.
3. Old or bad
version of Microsoft Data Access Components (MDAC). See below.
4.
Insufficient virtual memory allocated for large queries and data in
memory. See below.
To attempt to
resolve the errors of an Access Violation you should:
-
Update to
the latest release of ExpressMaintenance. This is not likely
to solve the problem but insures that you are running on the same
version as our tech support staff for the purpose of trying to
duplicate the problem.
-
Try to
duplicate the problem and note the first or any error preceding an
Access Violation error.
-
Check
your system memory and windows version by comparing to the
recommendations found in the above links. It is important that
you have the proper version of windows and amount of RAM.
-
Check the
installed version of the Microsoft Data Access Components (MDAC) at
the problem computer. You can check the MDAC version in
ExpressMaintenance under Utilities / View Connection Properties.
Version 2.6xxx of MDAC has some known problems. We recommend
that you have MDAC 2.7xxx or above. The MDAC may very well be
the cause of the problem. Once you download and install the
latest MDAC, use the steps above to verify the new version is
installed. To perform the installation, you must have
Administrative rights and you must reboot. You can check for
the latest release of MDAC and download it from the following link:

-
Check
your system virtual memory. The method of doing this varies
with different versions of windows. Generally, it can be found
under Control Panel / System / Advanced tab / Performance / Settings
/ Advanced tab / Virtual Memory. The system should be set to a
minimum of 512MB of virtual memory. This will allow for large
queries and having large amounts of data in memory.
If you have
taken the steps above and still have the Access Violation problem, try
to duplicate and provide email to our support technicians with the exact
steps to follow to reproduce the error. |
