Uninstall third-party antivirus
The first thing you should do when you encounter a problem is to uninstall the third-party antivirus program on your system. While security programs are really beneficial in keeping you safe from potential malware and whatnot, there are often cases where they cause certain problems due to a false positive. This is very common and almost happens to anyone who uses a third-party security program. ..
We recommend keeping Windows Defender on your computer because it has been very good over the years and receives updates frequently. If you are using a third-party antivirus, go ahead and uninstall it from your computer via Control Panel. You can also choose to disable it temporarily if you really don’t want to remove it. After doing this, go ahead and see if the problem still occurs.
Remove BitLocker or any other encryption
If you are using BitLocker or any similar software to encrypt your drives, and the installation cannot proceed because it cannot find the files to update, then you may need to contact your computer manufacturer or software provider for assistance.
If you have BitLocker protection on your computer, you will need to remove it in order to resolve the issue. Follow these instructions to do so:
Disable RealTek Drivers
If you are using Realtek drivers on your computer, it may sometimes cause issues with other devices. For example, if you are using a Bluetooth device, the Realtek drivers may not be able to connect to it.
If you are using a RealTek graphics card, you will need to disable the drivers in the Device Manager. This can be done by going to the Device Manager and clicking on the arrow next to the RealTek card name. Then select Manage Add/Remove Hardware. Underneath the Hardware tab, select RealTek from the list of devices. Once you have disabled the drivers for your RealTek card, your computer should be able to run games without any issues.
Uninstall .NET Feature

Change the safe boot operating system type
Secure Boot is a feature which is required by the Windows 11 operating system. To do this, you will need to have secure boot enabled. However, in some cases, you may have a problem with updates to your system when you have the OS type set to Other OS in the Safe Boot BIOS Settings.
If this case applies, you will simply have to boot into your BIOS and then fix the problem. The procedure may vary slightly for everyone depending on the motherboard you have, so we cannot provide fixed guidelines. However, the OS Type option is within the Safe Boot option in the BIOS settings, so keep this in mind. So, restart your computer and boot into the BIOS. Find safe boot and in the safe boot options change the operating system type from another operating system to Windows UEFI mode. After doing this, save your changes and restart your computer. After that, run the installation wizard again to see if the problem has been fixed.
update BIOS
If you change the operating system type on a safe boot, the options provided didn’t solve your problem. It’s likely that the problem is caused by outdated BIOS firmware on your edge. This is probably due to the fact that Windows 11 is a demanding operating system, as it requires installation requirements that we all know at this point. So if the BIOS firmware isn’t up to date, this may cause problems with the update process. ..
In this scenario, you will update the BIOS firmware to the latest version available for your motherboard. To do this, you’ll have to go to the motherboard manufacturer’s website and look for the card’s drivers. In most cases, there are manufacturer-supplied utilities available that you can use to install the latest BIOS firmware. After doing that, you can try running the installation wizard again to see if error code 0xc1900101 appears again or not.
