Hello Steve,
I wasn't able to find anything specific to the E-Mail Settings window and Dynamics GP crashing.
Along with Dynamics.dic, I'd rename any forms or reports dictionary files to see if any of those is causing this issue to occur.
If you haven't already, try another Dynamics GP install on another machine or at least another install on the same machine, with no third-party products or customizations to see if that also sees the same error. This will help us identify whether the issue is related to GP code or not.
Along with third- party programs and modified forms and reports, some things we normally look at for issues with Dynamics GP crashing are:
1. Make sure the antivirus applications are not actively scanning Dynamics GP's code folder and Dynamics.exe specifically, and has exclusions for the following file types:
• .cnk
These files are used when service packs are installed. These files should not be in a directory for a significant time.
• .dic and .chm
These files are the Help files for Microsoft Dynamics GP.
• .set
These files are the start files. These files contain information about the products that are installed and where the products are located.
• .ini
These files are the configuration files. These files hold information about which user logged on most recently, what data source is used, and the paths.
• .dat
These files are ctree .dat files that are used with an SQL database.
• .idx
These files are ctree index files that are used with an SQL database.
• .vba
These files are used if there are Microsoft Visual Basic for Applications (VBA) modifications for Microsoft Dynamics GP.
• .log
These files are used by a Dexsql.log file if you use a Dexsql.log file to troubleshoot an error message.
2. Run a Process Monitor trace to verify there are no Access Denied messages when the user re-creates the issue of Dynamics GP crashing.
3. Add Dynamics.exe as an exclusion in DEP:
A. Log into the Windows Server as an administrator
B. Right click on My Computer and select Properties
C. Click on Advanced System Settings
D. In the Performance section click Settings
E. Click on the Data Execution Prevention tab
F. select 'Turn on DEP for all programs and services except those I select'
G. Click the Add... button
H. Browse to the Dynamics GP folder and select the Dynamics.exe file, click Open
I. Click Apply to save your changes and click ok to close the window
Thank you,
