Troubleshooting

If you experience problems when using MBC4, check out the known problems and their solutions on this page.

If you do not find a solution, please send a full description using the "Contact Us" link above and we will invesigate.

Symptons:
Font Warning or Font does not appear in menu
Warning that a font is not installed

Problem:
Various causes

Explanation:

A number of fonts are supplied with the software for use in the human-readable text that sits below the bars (and/or elsewhere on the barcode). If the fonts are missing or not installed correctly, you may see a warning message.

Solution:

Ensure that the Computalabel fonts are stored in the Fonts folder that inside the Library folder that is in your User Directory.

Check that you do not have multiple copies of the same font installed.

Check that MBC4's access to the Computalabel fonts is not impeded by any third-party font management software.

Replacement fonts and fonts in alternate formats (Open Type, PostScript, TrueType) are available from Computalabel. Just let us know your MBC version number and the Mac OS version that you are using.

Symptons:
Unable to Install
Warning of failure to install by the installer

Problem:
Permissions Issue

Explanation:

MBC4 and it's associated files are stored in a folder which the installer creates inside your Applications directory. MBC4's fonts are installed in the Fonts folder inside your Library folder.

It is essential that you have permission to change the contents in these locations. If you do not, the installer will be unable to complete the installation.

Solution:

Check that you have permission to alter the Applications folder and the Fonts folder by creating a new folder inside them. If you are unable to do so, you will need to alter the permissions settings or the type of account that you are using. You will normally need an Admin account to install the software.

Symptons:
MBC4 Crashes
Serious Error warning

Problem:
Corrupt Preferences file

Explanation:

MBC4 stores your prefernces and settings in a file called "MBC4 Prefs" (or "MBC4.1 Prefs" if you are using MBC4.1.x, "MB4.2 Prefs" for MBC4.2x, etc.)

                   Prefs Folder MBC4
If the data in this file becomes corrupted, unpredictable errors may occur.


This problem is rare after version 4.0.1f4 when a self-checking routine was introduced.

Solution:

1. Quit MBC4

2. Locate the Prefs file. It will usually be found in the "Preferences" folder, inside the "Library" folder of your personal directory.

3. Remove the Prefs file from the Preferences folder. You may put it in the trash, or you might want to send it to us for further investigation.

4. Launch MBC4. Use the software as you would normally. Hopefully the fault will have been cured, but if it persists, contact us, describing the sequence of events leading to the crash or error message.

Note: When the Prefs file is removed MBC4 reverts to it's default settings. The barcode type will be EAN-13 or UPC-A and the Adjustment settings will have been reset to zero. It is most important that these settings are returned to their previous values.

 

 

 

 

 

 

Symptons:
Can't save files
Warning that barcode type is locked

Problem:
Registration file not installed correctly

Explanation:

When MBC4 launches it looks for a registration file inside the same folder.

This file contains the serial number which confirms your licence to use the software.

If the file is not found, MBC4 launches as a demo copy (you can't save barcodes).

           MBC4 folder

When you purchased MBC4, you would have been sent a registration file, either on CD or by email.

If you purchased MBC4.0.x, the file is called "MBC4 Registration".

If you purchased MBC4.1.x, the file is called "MBC41 Registration".

If you purchased MBC4.2.x, the file is called "MBC42 Registration".

If you purchased MBC4.3.x, the file is called "MBC43 Registration".

If you purchased MBC4.4.x, the file is called "MBC44 Registration".

If you purchased MBC4.5.x, the file is called "MBC45 Registration".

Solution:

1. Quit MBC4.

2. Locate the registration file that was sent to you (as a file on the CD or as an email attachment).

3. Drag the registration file into the same folder as the MBC4 application. This will normally be the "MBC4" or "MBC41" folder inside your "Applications" folder.
- you may be warned that a file with the same name is already in the folder. That is most probably the "demo" registration that was created when MBC4 couldn't find a valid registration file*.

4. Restart MBC4. You should now be able to save barcodes. Go to the "Unlock/Upgrade" screen item in the "MBC4" menu to check your available barcodes.
