If RED upgrade upgrades the repository option is chosen.

This enablement pack will overwrite any existing Source Enablement Pack UI Configs:

Connection UI Config	Load UI Config
Amazon S3	Load From Amazon S3
Azure Data Lake Storage Gen2	Load From Azure Data Lake Storage Gen2
Google Cloud	Load From Google Cloud

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 before 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.

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 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 hitting 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.ps1 Notes:

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>

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 Tip: to

Tip
To avoid having to provide all the parameters again you can copy the full command line with parameters from the first "INFO" message from the beginning of the console output.

Python requirements for offline install

Additionally to the base Python installation being required, the WhereScape Python Template set also requires certain additional Python libraries. The install scripts uses use the PIP (package manager) to download these libraries, however, for offline installs, you will need to install the required libraries yourself.
Required Python libraries/add-ons:

pywin32-ctypes
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 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.
