Solve Can’t Install Antivirus on Windows 10 PC

After knowing some of the causes above, here are some simple solutions that you can do.

#1. Make sure the Antivirus is compatible with your Windows

In installing software, you need to make sure that the software is compatible with the OS you are using. First, what OS version are you currently using? Is it 32-bit or 64-bit? If it’s 32-bit, then the software you install must be 32-bit, not 64-bit. As for the 64-bit OS, you can install 32-bit or 64-bit software. Everything can work well but will be more leverage when using 64-bit.

Well, also make sure the Antivirus program supports the type of Windows you are using, whether Windows 7, Windows 8, or Windows 10. Usually, on the official website, there are terms and conditions for installation. For now, most Antivirus such as Avast, Avira, Kaspersky, and others still support Windows 7. But in the future, it may no longer support it.

#2. UI Failed to Load

One of the errors that are often encountered when using Antivirus is ‘UI Failed to Load’. This happens with Avast Antivirus where the program crashes after opening or after installation. Actually, the program can be installed, but cannot be used at all. To solve this problem, you can go to the Service feature in Windows 10, then change the Startup type from Remote Desktop Service. Here are the steps;

1. First, please use the Windows + R keyboard shortcut combination.
2. Then enter the command services.msc then click Ok.
3. After that, find the Remote Desktop Service feature, and right-click» Properties.
4. In the Startup type section, change the setting to Automatic.
5. Then Apply and Ok.
6. Restart the computer and try to open the Antivirus again.
7. Finished.

#3. Uninstall Pre-installed Antivirus

Make sure you don’t install and use another Antivirus program when you want to install a new Antivirus. Because usually this also makes the installation fail or sometimes a message appears that you have used the Antivirus. Remove the Antivirus by going to the Add or Remove Program feature. Here are the steps;

1. First, please click your Windows 10 Start menu, then type Add or Remove Program. Click the feature.
2. Next, find the Antivirus program that needs to be removed. Click the program, and select Uninstall.
3. Confirm with Uninstall and follow the next uninstall instructions.
4. Finished.

#4. Turn Off Windows Defender

Before installing the new Antivirus, be sure to turn off ( turn off ) Windows Defender. Because in some cases, installing Antivirus or other programs is blocked by Windows Defender. Even though Windows Defender is also an Antivirus, many users are having problems installing the program. So you need to add an exception or turn it off for a while.

1. First, click the Windows 10 Start menu, then type Windows Security.
2. Once found, click the software.
3. Then select the Virus & Threat Protection feature, then select Manage Settings.

6. Finished.

#5. Clear Windows Cache

In addition to doing some of the things above, try to clean cache files and temporary Windows so that installed programs can run normally. Junk files that accumulate on the system also sometimes make the installation process problematic, you can use the built-in cleaner software such as Disk Cleanup to clean it. In addition, the author’s recommendation can use CCleaner. The software is very powerful and can clean the cache and registry faster and easier. If interested, please download it here.

1. To use CCleaner, open the program.
2. Go to the Custom Clean section, then check the programs you want to clean the cache, registry, and other temporary files.
