...

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.

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 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.

For upgrade of 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 the upgrade or manually run the wsl_post_install_enablement_pack script from the host script from RED after the upgrade.

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 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.
