...

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.

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 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>

Restarting failed scripts

...

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.
