Unable to create Instance - Core archive failed to download or unpack

OS Name/Version: Windows 10 22H2

Product Name/Version: AMP Instance Manager v2.6.2.6 built 04/08/2025

Problem Description: After downloading and installing AMP Instance Manager, upon opening and creating a username/password I am presented with this error after a short period.

Steps to reproduce:

  • Download latest AMP Instance Manager from CubeCoders
  • Run msi and allow it to install successfully
  • Launch AMP and create a username/password for the instance

Actions taken to resolve so far:

  • Re-downloaded MSI in-case of corruption
  • Tried different Windows 10 PC
  • Research indicated this might be due to application being unable to reach cdn-downloads.c7rs.com - /AMP/ but that URL is accessible from both PCs.
  • Created new Windows user
