Overview

The installation of GFI MailEssentials fails and one or both of the following errors are shown:

Product: GFI MailEssentials for Exchange/SMTP -- Error 1310.Error writing to file: C:\Program Files (x86)\GFI\MailEssentials\Antispam\MiddleLayer\GFICryptoStub.dll. System error 5. Verify that you have access to that directory. 

Product: GFI MailEssentials for Exchange/SMTP -- Error 1310.Error writing to file: C:\Program Files (x86)\GFI\MailEssentials\EmailSecurity\MiddleLayer\GFICryptoStub.dll. System error 5. Verify that you have access to that directory.

Note: This can also cause an issue with the Reports.mdb not being recreated after restarting the services.

Environment

• GFI MailEssentials
• All supported environments

Root Cause

User Account Control (UAC) was blocking access to the directory, thus not allowing the GFICryptoStub.dll to be installed and subsequently not creating the Reports.mdb.

Resolution

1. When prompted by the installation to Retry, Ignore or Abort, select Ignore.
2. Allow the installation to continue and complete.
3. Stop all MailEssentials services and set the Anti-Virus (AV) and Anti-Spam (AS) Scan Engines to disabled.
4. On your Virtual machines, locate the GFICryptoStub.dll file and attempt to copy it into the respective directory.
   Note: Step 4 may not be possible if there is an 'Access Denied' message. If this message is encountered, proceed to step 5.
5. Ensure that UAC is disabled and reboot the server.
6. Copy the DLL file into the relevant directory and restart the MailEssentials services.
7. If the issue was related to the Reports.mdb not being re-created, it should now be present in the ..\GFI\MailEssentials\Data folder and normal processing should resume.
