V15 - Installation Error: Source file not found

Introduction

Cause: Windows installer package manager not updated

Introduction

This guide is for 3CX V15 users that receive a Installation Error: Source file not found message while starting the 3CX installer.

Cause: Windows installer package manager not up to date

The cause for this is that Windows is unable to open extracted files from the 3CX EXE setup. In order to fix this go to Windows updates and give your machine all available updates.

This will happen on older operating systems such as Windows 7, 8 and Windows Server 2008 R2. Go to start ⇒ run ⇒ and type in wuapp.

Select all available updates and click on Install.” Upon the installation completed, reboot the host and re-check if any new updates are now available and repeat this process until none are available for install.
