There are 2 different solutions in this tutorial. Thus, it might seem too long to you. Don't worry! Most users could solve their errors by just following the first method. I think you'll be able to fix yours thanks to it. So you probably won't need to read the rest of the content. 😉
When upgrade installation is at 35 percent or 85 percent, an error with a blank page and the description below occurs like. You can see the full error window above.
The following things need your attention to continue the installation and keep your Windows settings, personal files, and apps.
Windows 11 Installation Stuck at 35%.
Windows 11 Installation Stuck at 85%.
The fixing method for all the errors I have shown above is the same: to follow the solution steps in this tutorial.
The causes of this error might be incompatible devices, drivers, games, programs, or waste files that need to be deleted when programs are uninstalling.
Normally, Windows 11 Update tool needs to list all these causes in this error window, but it doesn't do that.🤣
Don't worry! Fortunately, I'm here. 😊
When upgrading my Windows 10 to Windows 11 Insider Preview, I've encountered the same error, too. By following the solution steps I've shared here, I've been able to solve this error. So, I promise you will solve your error. 🤞
Here I will share all known programs and devices that are incompatible with Windows 11. Please share your program with us using the discussion form below to contribute to the development of this list. I've added the first program by my experience 😊
- VMware Player
- dnplayerext2 (A folder coming up with LDPlayer, but not deleted with it)
- NOX Player
- LinuxLive USB creator
Before starting, disconnect any non-essential external hardware like Bluetooth receivers of Mouse and Keyboards, external hard drives, printers, scanners, etc. connected to your computer.
Then, if you have one of the programs, such as VirtualBox, VMware Player, BlueStacks, LDPlayer, Nox Player, or TeamViewer, listed under the Known Incompatible Programs and Devices title, uninstall them.
Now, try to install again by clicking the
Refresh button on Windows 11 Update window.
If the error persists, you need to manually find the incompatible programs and files with Windows 11 in your current Windows.
I'll provide you 2 different methods to fix the error. Actually, they both do the same thing; however, according to our users' feedback, the most common problematic file is
virtualbox.exe; we'll focus on this file first. Even if you don't have VirtualBox on your PC, most emulators like LDPlayer or different kinds of programs might use this file in the background.
Firstly, search for
virtualbox.exe on your computer. If you could find it, you could determine the program name based on the parent directory. Then, uninstall the program and try to continue Windows 11 installation again.
You might see some .png icons containing
virtualbox.exein their names. We're not interested in them. Just focus on the .exe file that I've marked in the image. I've also underlined the parent directory (dnplayerext2) of VirtualBox.exe with two red lines.
You'll see the original VirtualBox.exe in the first mark. The second mark shows the parent directory of it. Click the up arrow icon that I've marked as 3rd, and go up to the container directory. In our case, it is Program Files.
In your case, the parent directory and the program may differ. For example, it might be
dnplayerext. If it is installed on your PC, you need to uninstall it first. If you don't know how to remove a program jump here.
Now, click the
Refreshbutton on Windows 11 Update window and wait
If everything is OK, congratulations! 👏 Otherwise, you need to find the incompatible file or program manually by following the steps in the next method. Continue.
Open Start Menu and type "File Explorer Options", then click on it in the search results.
Windows logs the incompatible programs and files in a hidden XML file in different folders in commonly C:** drive. Thus, in order to find and see these files, we've changed the **Hidden files and folders setting.
Windows Search might found multiple files. It's ok. We'll examine all of them. Actually, if we'll find a problematic file or program in a log file, only removing it may fix our error, but I recommend checking all files one by one. Alternatively, after finding a problematic file or program, remove it. Then, try Windows 11 Update again by clicking the
Refreshbutton. If the installation continues, you don't need to check other log files. You can follow this method one by one if you don't want to spend a lot of time on all log files. 😉
Fcombination on your keyboard to open the search bar on your editor (Notepad, Notepad++ or VSCode).
DT_ANY_FMC_BlockingApplicationValue="TRUE"` and search. It means there is a problem with this file or program that the Value attribute is TRUE. Well! Where is the program or file?
Scroll down a bit and try to find the
LowerCaseLongPathUnexpandedproperty with your eyes. This property is 28 lines below the property we just found, (DT_ANY_FMC_BlockingApplication). You'll see the location of the problematic file or program in the Value attribute of this property something like that:
In my case, the problematic program was LDPlayer, as you can see above. Because there is a %programfiles% indicator at the beginning of the value, I understood that the ldplayerbox directory in the C:\Program Files directory. Moreover, I could see that it is a program.
Then I've checked manually whether all files of LDPlayer have been removed to make sure that everything is OK. If your problematic files in Program Files directory like my case, and if the program is not necessary, I suggest you uninstall it for the best solution. Then go to the program's directory in Program Files, check whether it has been removed completely. If not, delete it manually. If you don't know how to uninstall a program, you'll find an uninstallation guide below.
If the error persists, please make sure that you've found and removed all problematic programs in all log files that we've found by Windows Search.
Restart your PC. Then, welcome to Windows 11 😍 ✌
Type "Add or Remove Programs" on Start Menu. Then click on it.
Go to the program's directory in Program Files or Program Files (x86) depending on the architecture of your program.
