If RED upgrade 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 prior to installing this Enablement Pack and rename the affected UI Configurations. While the updated Load Template will work with previous Source Enablement Pack's we recommend moving these previous 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

1. open it's its properties and check the extended properties tab, set it up for SERVER_NAME and SERVER_PORT
Connection: 'Database Source System' - this connection was setup set as an example source connection,
1. open its properties and set it up for a source DB in your environment
2. or you can remove it if not required

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 "select Run As Administrator"
Now you have an admin prompt navigate to to the folder where you have unpacked your WhereScape Red Enablement Pack to using the 'cd' command:
C:\Windows\system32> cd <full path to the unpacked folder>
Run batch (.bat) scripts from the administrator prompt by simply typing the name at the prompt and hit clicking enter, for example:
C:\temp\EnablementPack>install_WslPowershell_Modules.bat
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.ps1Notes:

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 a number of several workarounds for this which can be found by searching the term "Powershell Execution Policy".
Here is the most common workaround which 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>

Re-install Python Libraries

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 "select Run As Administrator"
Now you have an admin prompt navigate to to the folder where you have unpacked your WhereScape Red Enablement Pack to using the 'cd' command:
C:\Windows\system32> cd <full path to the unpacked folder>
Run batch (.bat) scripts from the administrator prompt by simply typing the name at the prompt and hit enter, for example:
CC:\temp\EnablementPack>uninstall_WslPython_Modules.bat
For the installation of Python libraries, there are two methods

Method 1
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

...

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> folder> Run the below command
python -m pip install -r requirements.txt

For upgrade of an existing repository

In the upgrade of exiting the existing repository if the user gets the above error then it means the script type of of wsl_post_install_enablement_pack is set to PowerShell(64-bit) change the script type to Auto Execute-PowerShell before upgrade or manually run the wsl_post_install_enablement_pack script from host script from RED after upgrade.

...

If you have RED 10.x or higher installed but the script (Setup_Enablement_Pack.ps1) fails to find it on you 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
Table name should be given in lowercase only
While loading the table, the table name should be given in lowercase, for example, load_tablename; otherwise, loaded data will now get displayed.
