The ExportZen setup package (the roxority_ExportZen.zip file) is a zipped archive containing:
Run Deploy.exe (under user account credentials added to the Farm Administrators group in Central Administration, on the "primary" SharePoint farm or web front-end server — in a multi-server farm environment, that is the server hosting Central Administration) and when the Welcome screen is displayed, click Next to start a series of system checks. To proceed with the installation, all system checks need to succeed:
Click Next and on the following screen, select the Web Applications to deploy ExportZen to. You can also de-select those Site Collections you do not want the setup wizard, upon successful deployment, to activate the ExportZen List Integration feature immediately for you on.
Click Next to start the installation and wait for the deployment jobs and Feature activation to complete. This process can take up to a few minutes.
After deployment and Feature activation have completed, review the installation log:
Once you have successfully completed the setup wizard, you can start defining Export Actions (via Site Settings / ExportZen Studio) immediately, as described in the Using the ExportZen CSV Data Export Feature for SharePoint Lists introductory topic.
The ExportZen List Integration feature is a SharePoint Site Collection-scoped Feature, which needs to be 'activated' on each Site Collection it is to be used in.
This feature needs to be activated if your Export Actions (defined under Site Settings / ExportZen Studio) should be offered to end users (via the "Actions" List toolbar menu and the "Connect and Export" ribbon group) to facilitate interactive invokation of your Export Actions.
The LegacyMigration.exe tool is needed if you intend to upgrade ExportZen from a previously or currently installed version lower than 1.6, to 1.6 or higher. Deploy.exe will detect whether the tool needs to be run in your environment, and inform you accordingly.
If this upgrade scenario applies to you and you haven't uninstalled ExportZen yet, good — don't do so until you have completed this tool successfully.
Prior to 1.6, ExportZen used its own List definition and custom field types so that ExportZen action definitions could be set up by admins and power users. Starting in 1.6, this overhead is no longer necessary, but keeping Lists and their Columns based on these legacy types in your content database WOULD compromise your SharePoint environment after upgrading to 1.6 because the underlying List definitions and Column types are no longer there.
It is therefore crucial to not just recycle but fully delete these legacy Lists. The LegacyMigration.exe tool first scans your entire SharePoint server farm for these legacy Lists when you click the scan button on the left. This first step is definitely completely harmless.
After the scan completes, all legacy Lists found are shown in the view on the left. Click the Backup/Export button on the right to first save all your export action definitions from your earlier installation to a file that you will be able to fully import (via Site Settings / ExportZen Studio / Transfer Wizard) into ExportZen 1.6 or higher later after the upgrade has been performed. This button will then attempt to delete all legacy Lists found, and will notify you about its success. All these legacy Lists will need to be deleted or the ExportZen deployment wizard (Deploy.exe) will simply refuse to perform the upgrade to 1.6 or higher.
