"Fatal error during installation" error message appears when installing ScanMail for Exchange (SMEX)

    • Product/Version:

When installing SMEX, the error message "Fatal error during installation" appears when the administrator changes the shared directory drive letter that is specified in the Configure Shared/Target Directory step of the installation wizard.


Directory Share is used to copy SMEX install files/folders during setup. These files are removed automatically when the setup is done. The default temporary shared directory is "C$" in all Windows platforms.


The error appears when there are insufficient user access rights on the specified drive, as shown by this sample snippet of the SMEX_RIFRemoteInstallAgent.log:

When the drive letter is changed to another shared drive, make sure that it has the Read/Write/Execute security permissions for both local Admin and ExOrgAdmin users to avoid installation problems. Otherwise, just leave the default shared drive "C$", which is already configured with the required access rights for local/domain administrator accounts.

Below are the installation log/s directories, for further reference.

Remote Server:

  • {System temp}\SMEX_RIFRemoteInstallAgent.log
  • {SMEX Installed folder}\Debug\All log files
  • {SMEX Installed folder}\SMEX_DatabaseCreation.log
  • {System temp}\instDetectClusterType.log

Local Server:

  • {Logon user temp folder}\setup.log
