I am attempting to upgrade it to DNN 8.0.3. Every time I've tried, it gets to 52% and then an error occurs when it attempts to install DNNCE_GoogleAnalytics_08.00.03_Install.

I unblocked the upgrade package before extracting it.

I have made sure that the App Pool user has Full Control permissions to all files and folders in the site assets.

Also I have check Event log and getting below issue.

<LogProperty>

How to resolve this issue. Also give suggestion related to upgradation for 7.3.2 to 8.0.3 version.
