Fixing Windows 10 installation errors



  Windows 10 installation error message log on the desktop

The Windows 10 installation and upgrade process sometimes fails and says your PC can not be upgraded, but no action is required. Windows knows the problem, but Microsoft hides the problem details from you. Here's how to identify and fix the problem yourself.

Reading "What to Remember"

  Things to Remember Windows 10 Setup Error

Microsoft should provide more meaningful error messages. The message we saw while trying to update to the Windows 10 update from May 2019 using the Microsoft Update Wizard was:

This PC can not be upgraded to Windows 10.

A driver or service is not available on your PC This version of Windows 10. No action is required. Windows Update automatically offers this version of Windows 10 once the problem is resolved.

According to Microsoft, the message "No Action Required" means you should not do anything.

That's all right and fine, but what if you do not want to wait Why does not Windows tell us which "driver or service" is causing the problem? Windows 10 knows the problem, but does not show it here. You need to extract it from the log files and fix it yourself. Here's how it works:

Viewing Windows Setup Log Files

The log files are hidden in this folder on your PC:

  C:  $ WINDOWS. ~ BT  Sources  Panther 

To locate it, open a file explorer window and copy that address to the address bar.

 Windows 10 setup error log Panther folder

Find a file name that starts with "CompatData_" and ends with ".xml" in this folder. If several are displayed, you should select the newest one – the one below.

 CompatData file in the Panther folder of Windows 10

Open the file to view the contents. Without additional software, we recommend clicking the file with the right mouse button and selecting Open with> Microsoft Edge.

You can also view them with Notepad ++. Notepad and WordPad display the file, but without the additional formatting provided by Edge and Notepad ++, reading is difficult.

 Opening a CompatData XML log file on Windows 10

This file tells you why Windows is not being updated – if you can decode it.

For example, to find drivers that are incompatible with DriverPackages, use the following lines:

  BlockMigration = "True" 

 Locate a driver that blocks migration on Windows 10

This indicates that the drivers associated with the oem81.inf and oem80.inf files are not compatible with the new version of Windows. That's why Windows refuses to upgrade.

But what are these files?

Customizing a driver to an .inf file

To learn more, you must open the log in the named .inf files. They can be found at:

  C:  Windows  INF 

Browse the folder and locate the .inf files to examine. In our case this is oem80.inf and oem81.inf.

 OEM INF files in the system folder of Windows 10

You can double-click on them to open them in the editor. In that case, you'll probably see a comment at the top of each file explaining what it is.

In our case, it turned out that oem80.inf was the Microsoft Print To PDF installation file and oem81.inf was "The Microsoft XPS Document Writer Installation File." In other words, Microsoft's own XPS and PDF printer driver part Windows 10 – block the installation process for some reason.

 How to Fix the Problem [196909011] After we know the problem, we can fix it by uninstalling the faulty driver. </p>
<p>  In this case, we can do this under Control Panel> Programs> Turn Windows features on or off. Disable both "Microsoft Print to PDF" and "Microsoft XPS Document Writer" and click "OK." They can be reinstalled later after the upgrade. </p>
<p>  If other hardware drivers or applications block the upgrade, you can temporarily uninstall it </p>

Resume the upgrade process

You may be able to use the Windows 10 Setup window after clicking the "Refresh" button you have solved the problem. We are sorry! That will not do. The Refresh button will not work.

Instead, you have to go to C: $ WINDOWS folder. ~ BT Sources Panther return. Locate the file compatscancache.dat and delete it.

 Deleting the compatscancache.dat file to continue the update process

After deleting this cache file, you can click the "Refresh" button and the installation process continues.

"Something's happened"

This is the process that Microsoft has given us, it's not that great. As Brad Sams puts it, this bug reporting system is a "cryptic mess". The name of the folder "Panther" comes from Windows Vista – that's how old it is!

The Windows 10 update from May 2019 should perform better than setup error messages, but we do not see them yet. At least this is better than the old messages "Something has happened".
