Can't update window to window 20h2

Thank you so much.... Looking at the "HumanReadable" file help a lot.

For me it wasn't a linuxlive it was that when I updated Virtualbox I would make a backup of the program folder to the same folder. Once I moved them out the update was able to continued.

That works for me, many many thanks !

This did it for me. Deleting LDPlayer allowed update to continue, Thank you sir!!!

HI all .Quite frustrating but i solved the problem like this.  

VIrtualBox prevented the update.  Could it be the case????????

I downloaded from the lower link  the zip file ( mentioned in other replies )

https://www.majorgeeks.com/files/details/uninstall\_this\_app\_now\_powershell\_script.html

I run the appraiser.bat as ADMIN and it run PSI script that came along in the zip file and although it didn't work because of  null path  it helped me quite a lot.

I went to C:$WINDOWS.~BT\Sources myself and i found the files that were mentioned ending in *_APPRAISER_HumanReadable.xml.

The "BLOCKING APPLICATION" was in specific flles     bla_bla_bla_APPRAISER_HumanReadable.xml and and also mentioned a line .

I opened the files with notepad++ and i went at their  specific problematic  line (ie 155521 for one 157443 for the other ,  e.t.c  ) i saw  something like 

<Property Name="DT_ANY_FMC_BlockingApplication" Value="TRUE" Ordinal="1" />  

Some people commented to find such a line putting in the search box of notepad    " DT_ANY_FMC_BlockingApplication"   and change the Value from FALSE to TRUE. Weird . Mine was already  TRUE !!!!  All lines in all files !! ( 6 files in my case) 

I never believed that VIrtualBox was the problem because is a MAJOR application for us all. Also some people never had it installed~!

So i just scrolled down  a little from the problematic line to see if i could see what the problematic applicaition was 

And voila !!!!

after 20 lines in ALL files i found the Problematic application.

For me i saw this in all files

<Property Name="LowerCaseLongPathUnexpanded" Value="\liberkey\myapps\linuxlive usb creator 2.9.4\tools\virtualbox\portable-virtualbox\app64\virtualbox.exe" Ordinal="1" />

In my liberkey i had USB creator   from here https://www.pendrivelinux.com/tag/portable-virtualbox/   .

I simply Uninstalled the USB creator along with the folder and OF COURSE kept the original virtualbox app from ORACLE.

Desktop and laptop pc's updated like a charm !

In conclusion find the files , and  the specific line that are  mentioned in PS1 script , scroll a little and find the problematic file. 

Delete or uninstall and that's it .

I hope that helps 

Cheers
