The user will be directed to the window below, where they have to select the target connection to be configured. Additionally, by deselecting the provided options, the user can choose not to install a particular option.
You will be directed to the PowerShell window below. Provide the directory that contains the unzipped Enablement Pack.

Upgrade Of Existing Repository
For upgrade of an existing repository
- From the host script set the script type of
wsl_post_install_enablement_packas Auto Execute- PowerShell Script
Important Upgrade Notes
If RED upgrades the repository option is chosen.
This enablement pack will overwrite any existing Source Enablement Pack UI Configs:
...
To ensure existing Source Enablement Pack connections and associated Load Tables continue to browse and load:
Go into UI Configuration Maintenance in RED before installing this Enablement Pack and rename the affected UI Configurations. While the updated Load Template will work with the previous Source Enablement Pack we recommend moving these earlier versions of Load Tables to newly created Parser-based connections following this install. The earlier versions of the Source Enablement Pack will be deprecated following this release.
Post Install Steps – Optional
If you used the script Setup Wizard for installation then the following optional post-install steps are available.
Configure Connections
There were two connections added that will optionally require your attention:
- Connection: 'Database Source System' - this connection was set up as an example source connection,
- open it's properties and set it up for a source DB in your environment
- or you can remove it if not required
- Execute Update Procedure for dim_date_or to Initialize Date Dimension for Target
| Note |
|---|
Please avoid regenerating the procedure update_dim_date_or as it is a custom procedure. |

Troubleshooting and Tips
Run As Administrator
Press the Windows Key on your keyboard and start typing cmd.exe, when the cmd.exe icon shows up in the search list right click it to bring up the context menu, select Run As Administrator
Now you have an admin prompt navigate to to the folder where you have unpacked your WhereScape Red Enablement Pack using the cd command:C:\Windows\system32> cd <full path to the unpacked folder>
Run Powershell (.ps1) scripts from the administrator prompt by typing the Powershell run script command, for example:C:\temp\EnablementPack>Powershell -ExecutionPolicy Bypass -File .\Setup_Enablement_Pack.ps1
| Note |
|---|
In the event you can not bypass the Powershell execution policy due to group policies you can instead try "-ExecutionPolicy RemoteSigned" which should allow unsigned local scripts. |
Windows Powershell Script Execution
On some systems, Windows Powershell script execution is disabled by default. There are several workarounds for this which can be found by searching the term "Powershell Execution Policy".
Here is the most common workaround that WhereScape suggests, which does not permanently change the execution rights:
Start a Windows CMD prompt as Administrator, change the directory to your script directory, and run the WhereScape Powershell scripts with this command:
- cmd:
>Powershell -ExecutionPolicy Bypass -File .\<script_file_name.ps1>
Restarting failed scripts
Some of the setup scripts will track each step and output the step number when there is a failure. To restart from the failed step (or to skip the step) provide the parameter -startAtStep <step number> to the script.
Example: Powershell -ExecutionPolicy Bypass -File .\<script_file_name.ps1> -startAtStep 123

- python-tds
- pywin32
- glob2
- gzip-reader
- regex
- pyodbc
If a valid RED installation can not be found
If you have RED 10.x or higher installed but the script (Setup_Enablement_Pack.ps1) fails to find it on your system then you are most likely running the PowerShell (x86) version which does not show installed 64-bit apps by default. Please open a 64-bit version of Powershell instead and re-run the script.
