Error message when you try to start Microsoft Dynamics GP on a computer on which named printers are enabled: "Application must close"

To resolve this problem, temporarily disable named printers on the computer so that the default printer for Microsoft Dynamics GP is not changed when you start the program. Next, start Microsoft Dynamics GP, and then set up named printers correctly. After you do this, enable named printers. To do this, follow these steps:

1. Double-click the Dex.ini file.
2. In the file, locate the following line:
   ST_SetDefault=TRUE
3. Change the value of the ST_SetDefault parameter to FALSE.
4. Save the changes, and then close the file.
5. Start Microsoft Dynamics GP.
6. On the Tools menu, click Setup, click System, and then click Named Printers.
7. Change the settings for the default printer for the System task series so that you specify a printer that exists.
8. Change the settings for the default printer for the Company task series so that you specify a printer that exists.
   
   Note This step is optional. You only have to do this if a default printer for the Company task series is already set up.
9. Exit Microsoft Dynamics GP.
10. Double-click the Dex.ini file.
11. Change the value of the ST_SetDefault parameter to TRUE.
    
    

Note You can temporarily disable named printers by putting a semicolon in front of the ST_MachineID= setting in the Dex.ini file instead of setting the ST_MachineID= setting to FALSE.
