PROACTIVE Easy step-by-step guide to solve patching issues
Created this thread to proactively help customers with errors during patches. We included most of the errors you can receive.
Try to dig as much as possible.
Avoid receiving usual questions and prove you already did 90% of investigation.
Provide us all needed information (you will find here what you have to give us) and we will probably answer from the first update!
Note! The investigation steps are regularly updated !!!
