Going through Trailhead and wanted to install the Visual Workflow Getting Started Pack.

App Name
Visual Workflow Getting Started Pack
Publisher
Salesforce Labs
Version Name
2.1
Version Number
2.1

When I tried, I got the following errors:

Contact_Form-1: Email_Address (Screen Field) - The formula expression is invalid.

Run_Invoice_Request_Form-2: Run_Invoice_Request_Form (Subflow) - The flow Invoice_Request_Form doesn't exist.

Convert_Lead_Apex_Plug_in_Sample-1: Email_Address (Screen Field) - The formula expression is invalid.

I've tried installing in production (I don't have a sandbox) as "Install for Admins Only", "Install for All Users", and "Install for Specific Profiles..." and the same error comes up.

See attached screen shot.

Any advice? Thanks!
