HI,
I have run the prescan and it did not find any errors in package and other 2 scans. I will try to run the readiness tool. This is the latest i downloaded from the site.
I checked the event viewer, not when running the readiness tool. But it is taking some time to load the logs. I could find red and yellow marks in application log. But there is no log regarding window updates.
I will still try to run the tool again and report to you
