Answer

IMPORTANT: Installing the Archive Assistant on a terminal server / Citrix server is currently not supported from the Archive Assistant installer.

PROBLEM

The Archive Assistant cannot be installed on a terminal server or Citrix server. When a user tries to install the Archive Assistant, the following error is shown:
 

ENVIRONMENT

• GFI Archiver
• Trying to install the Archive Assistant on a terminal server or Citrix server

SOLUTION

The Archive Assistant can be registered manually. This can be tied together in logon scripts for automation in general.

1. To register the Archive Assistant manually the following steps need to be performed from a high level view.
2. Setup a group policy object (GPO)  in Microsoft Active Directory to configure the GFI Archiver URL used by the Archive Assistant
3. Perform a clean installation the Archive Assistant on a regular workstation
   • It is important to keep the bitness of Microsoft Outlook used in mind here. For example, if the target systems run a 32bit Microsoft Outlook use a regular workstation with the same bitness for this step.
4. Collect installation files from the clean installation
   • Installation folder: %appdata%\GFI\MailArchiverAddon\
5. Copy the installation files to the target user profile on the target machine
6. Download the following file:
   • GFI Archiver 2015 and 2015 SR1: http://ftp.gfisoftware.com/support/MARC/ScriptsAndTools/2015/ARC2015_ADXRegistrator.zip
   • GFI MailArchiver 2014: http://ftp.gfisoftware.com/support/MARC/ScriptsAndTools/2014/MARC2014_ADXRegistrator.zip
   • GFI MailArchiver 2013: http://ftp.gfisoftware.com/support/MARC/ScriptsAndTools/2013/MARC2013_ADXRegistrator.zip
7. Extract it, then run the executable on the target machines
   • adxregistrator.exe /install="MArc.Outlook.Addon.dll" /privileges=user

Notes

• Steps 4 - 6 can be automated in a logon scripts in general, but how this can be done is not outlined in this article.
• In case uninstallation is required, the following command needs to be run:
  • adxregistrator.exe /uninstall="MArc.Outlook.Addon.dll" /privileges=user

CAUSE

The Archive Assistant is a "per-user" installation. Due to terminal server / Citrix server handling permissions differently, the installation cannot be performed unless you grant all users permission to install software on the server, which is not recommended.
