Troubleshooting

Unable to Run NCache PowerShell Cmdlets

This occurs if the environment variable PSModulePath has not been refreshed after the installation. Import the NCache PowerShell module (ncacheps.dll) found in the location %NCHOME%\bin\tools\ncacheps.

Execute the following command on Windows PowerShell to import the module:

Import-Module -Name ncacheps

In order to verify if the environment variable PSModulePath has been refreshed successfully, run the following command using Command Prompt (Run as Administrator).

echo %PSModulePath%

On running the following command, the path for ncacheps gets displayed. If the output displays %NCHOME%\NCache\bin\tools it means that the environment variables are refreshed.
