I tried integrating Salesforce with VS code.. I installed Salesforce CLI and when I tried creating a project in VS code but it says that Salesforce CLI is not installed.
 The exact error is

"14:48:25.402 sfdx force:project:create --projectname TestProject --outputdir d:\ --manifest
'sfdx' is not recognized as an internal or external command,
operable program or batch file.
