Environment

Release : 20.3.3 

Component : UIM - ADE

Cause

- After unzipping, the customer accidentally replaced the larger size installer package with the smaller size package, which caused the installation to fail.

Resolution

This is related to uimserverpackages.zip file.

1. Check to make sure that the uimserverpackages.zip file is the right size.

2. If it is corrupted, it will cause an issue like this.

3. Verify the package is the correct size and rerun the installer.
