Some computers may require DEP settings turned off for Infusion. To determine if a computer requires this log into Infusion and try to open and re-save an existing record. For example, a Customer Account, or a Product Code. You may get an error saying “Fatal Error – Visual Fox Pro has stopped working” with the specific EXCEPTION CODE c0000005, c0000006 or 0xc000005 or secondary error code 0xc000041d, or Infusion may just close with no error reported.

It is recommended that you confirm the path that is causing the error by checking Windows Event Viewer.
Open Event Viewer and go to Windows Logs > Application.

Identify the first error relating to Infusion.  Start by excluding this file.  (it may be parallelfox.exe or ibsapp.exe).  Note the path to the file and exclude that exact file.   Then open Infusion, save a record, if there’s still an error, check the Event viewer again for the first error and which file is causing the error.

If you can Save a Record, it is not a DEP error, do not set DEP exclusions even if other users require it. If the error occurs as the subsequent action after sending an email from the Preview screen, it is not a DEP error.  This error has been fixed in version 8.515, please upgrade.

How Do I Exclude ISBAPP from DEP

Standard Setup

Open Windows Explorer

Right Click on This PC, click Properties and select Advanced System Settings

Select Settings

Select Data Execution Prevention

Select Add and then browse to the IBSAPP.EXE  path that was showing in the Event Viewer error.

 

• Depending on the PC settings you may need to restart the PC after making these changes
• Networks with a mixture of Windows 10 and 7 will need to set DEP on all Windows 10 machines. 

How Do I Exclude IBSAPP from DEP? Advanced Setup

If the basic setup did not work we recommend removing all DEP settings and starting again.  Use the following procedure:

Identify any current or leftover DEP settings

Open Regedit as Administrator.

Navigate to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

Delete any values that seem linked to Infusion.  They should have DisableNXShowUI as their value.  Contact Infusion Support if you are unsure.

Open the DEP Settings as per Standard Setup above.  (In Windows Explorer: Right click on This PC > Properties > Advanced System Settings > Settings (Performance)  > Data Execution Prevention)

Remove any Accounting Application or ibsapp.exe or parallelfox.exe settings and select Apply then OK.

Restart the PC

Open Infusion Open and Save a customer record.  If this is successful, restart the PC and check again.  If either of these fail and you still cannot complete a Standard Setup as above:

Either the Mapped Drive is not available: See If you can’t see the Mapped Drive – EnableLinkedConnections – Windows 10; or

The User is not logged in as an Administrator – see If the Logged in User is not an Administrator below:

If you cannot see the Mapped Drive in the DEP settings:

Open Regedit as Administrator.

Navigate to:

HKEY_LOCAL_MACHINE/SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

and create a new DWORD entry with the name EnableLinkedConnections and value 1

Exit Regedit and Restart the PC.

Set the DEP Settings as per the Standard Setup.

Open Infusion – open and Save a customer record.  If this is successful, restart the PC and check again.  If not:

If the Logged in User is NOT an administrator:

No matter what you do to set the DEP settings, they won’t “stick”.  If you’re having to ask the user to put in Admin user and password all the time, then the ‘everyday’ user is probably not an admin user.

1. Check the mapped drive path on the everyday user (eg. ACME1). Make a note of the exact mapped drive.  (eg. Z:/Accounting/Infusion)
2. Switch users on the workstation to the Admin user.
3. Set up a mapped drive which exactly matches the ACME1 user.  (using Z:\Accounting will not work,  it is not the same address so the DEP settings won’t work for the ACME1 user).
4. Set the DEP settings for that mapped drive to ibsapp.exe as normal.   *(NB the DEP exclusion did not state “Accounting Application” as it normally does – unsure why)
5. Check Infusion from Admin user, save a customer.  If ok, Switch user:
6. Open Infusion as ACME1 – all ok? Then Restart the PC and check again.
