Title
V-MAC III Service Software Displays Runtime Error 400 - Form Already Displayed
(Modality)
Cause
1. Data link adapter settings are locked in indeterminate state, and/or
2. Data link adapter driver [Noregon Standalone API] is installed improperly, and/or
3. V-MAC Service Software is installed improperly, and/or
4. PC/data link adapter combination is untenable or unusable.
Solution
NOTE: Before undertaking the corrective action outlined in this Tech Tip, you
may want to try a different data link adapter and/or a different chassis to make
sure that the problems you are experiencing are not data link adapter or chassis
specific.
Corrective Actions:
1. Step 1: Attempt to set V-MAC Preferences directly using the MACK Configuration
Manager.exe applet as follows:
a. Select OK and let the offending application terminate abnormally.
b. Navigate to the C:\Program Files\Mack Trucks, Inc\Shared directory.
c. Double-click on the file Mack Configuration Manager.exe ; you will
see the following data link adapter selection dialog box:
d. Set all data link adapter selection criteria properly (this will vary
according the data link adapter and operating system employed).
e. Select Apply, and then OK.
f. Close the computer browser, connect the PC to any Mack chassis, and
attempt to launch the offending application once again. Diagnostic
application operations should proceed normally at this point.
2. Step 2: If the preceding instructions fail to deliver consistent and reliable PCto-chassis communications, uninstall and reinstall the Noregon Standalone API
as follows:
a. Navigate to Control Panel Add/Remove Programs, and uninstall the
Noregon Standalone API.
b. Before restarting the PC, search for the file RP121032.ini, and delete
any found.
c. Close any open windows applications and restart the PC.
d. Reinstall the Noregon Standalone API, allow the PC to restart once
again, and then follow the instruction outlined in Step 1 of this Tech Tip.
Diagnostic application operations should proceed normally at this point.
3. Step 3: If the instructions contained in the preceding two steps fail to deliver
consistent and reliable PC-to-chassis communications, it is possible that the
installation of V-MAC Service Software is corrupt. As a result, it will be
necessary to uninstall Mack Trucks, Inc., diagnostic software, the drivers
outlined in Step 2, and perform the operations outlined in Step 1, setting V-MAC
Preferences directly:
a. Navigate to the Control Panel Add/Remove Programs applet, and
uninstall any instances of V-MAC III Service Tools and/or V-MAC
Dealer Programming Software.
b. When finished, use My Computer or equivalent to navigate to the C:
\Program Files directory and delete the Mack Trucks, Inc subdirectory.
c. Uninstall and reinstall the Noregon Standalone API as outlined in Step
2 of this Tech Tip.
d. Reinstall V-MAC Service Tools software.
e. Set V-MAC Preferences directly as outlined in Step 1 of this Tech Tip.
Diagnostic application operations should proceed normally at this point.
4. Step 4 - If all of the instructions provided to this point have failed to deliver
consistent and reliable PC-to-chassis communications, chances are that you are
not utilizing a diagnostic PC as specified in the Mack Trucks, Inc.,
Recommended Field Service PC Program (SB # 221-039). Even if this is the
case, the state of the PC/data link adapter combination either is or has become
untenable and/or unusable. You can:
a. Reformat the PCs hard drive and start over from scratch, or
b. Upgrade your PC to one specified by the Mack Trucks, Inc.,
Recommended Field Service PC Program (SB # 221-039), or
c. Upgrade your data link adapter to one designed to use other than the
PC's serial port (most communications issues are the result of a poor
serial port I/O implementation). Please contact the Mack Trucks, Inc.,
Reliability Engineering Department at (610) 709-2448 for further
instructions and/or recommendations.
