Issue/Introduction

When upgrading or installing UIM 20.4, the installer sticks at 5% on the "installing uimserverpackages.zip" stage and never makes any progress.  We have waited 15 minutes with no movement.

Cause

Antivirus

Resolution

Issue was determined to be caused by Symantec Antivirus performing a weekly scheduled scan during installation time.

Snoozing the scan immediately allowed the installation to proceed past the 5% mark and complete successfully.
