Some programs may require you to restart your PC after installation in the system for the modifications to apply the effect. As a result, restart your computer if the installed program prompts you. That’s all there is to it; the program has been reinstalled on your computer. It should now start operating correctly.

Certain versions of the framework are likely already installed on your PC. However, re-enabling the framework may resolve the ‘mscoree.dll not found’ issue.

Enable .NET Framework 3.5 Using Command Prompt

It is quite easy to enable the framework using the Command Prompt. It simply takes a handful of commands to execute, and you’ll be done before you know it.

1 – Navigate to the Start Menu and type Terminal to find it. To proceed, right-click on the Terminal title in the search results and select the ‘Run as administrator’ option.

If the error was caused by a recent update or the installation of third-party software, you should no longer experience the ‘mscoree.dll not found’ issue.

Use Registry Cleaner

Although this is an extreme step, it is one of the final options before the total nuclear solution, which is the next step. If nothing else has worked, you may try repairing the mscoree.dll issue in the registry using a registry cleanup tool. The Windows registry is a database file in Windows that stores a list of DLL file references on your system. This is the database to which Windows consults whenever it needs to locate a DLL file, such as the mscoree.dll file. However, the registry file might get damaged or corrupted, making it difficult for Windows to read the needed file and thus causing all of the commotions. There are several free tools available, like CCleaner, Wise Registry Cleaner, and others, that you may use to remove any invalid mscoree.dll registry entries in the file that may be causing the issue.

Perform Clean Install Of Windows

If none of the alternatives above work for you, the only way to resolve the error is to factory reset your PC. However, as the name implies, this will remove all files, folders, and settings from your PC and bring it to factory condition.

1 – To proceed, go to the Start Menu and click on the ‘Settings’ title beneath the ‘Pinned apps’ section. Alternatively, start the Settings app by simultaneously pressing the Windows+I buttons on your keyboard.

2 – Now, on the left side of the ‘Settings’ window, click on the ‘System’ option.

3 – Next, scroll down and locate the ‘Recovery’ option. Click on it to enter the ‘Recovery’ settings.

4 – Click the ‘Reset PC’ button on the ‘Recovery Setting’ screen to continue.

5 – A new window will open after clicking the ‘Reset PC’ button. You would now have two options on the independently opened window:

Keep My Files – As the name implies, choose this option if you want to keep your files while all system apps are removed and system settings are reset to a new state.
Remove Everything – This comes as no surprise. This option will remove all photographs, programs, and apps and restore the operating system to its original condition as if it were brand new. This option is advised due to the nature of the problem.

6 – For the sake of this instruction, we’ll select the ‘Remove everything’ option.

7 – After choosing one of the options, the following window will prompt you to select either a ‘Cloud download’ or a ‘Local reinstall’ option. ‘Cloud download’ is more trustworthy and stable than ‘Local reinstall’ due to the likelihood of corrupted or damaged files.

However, as the name implies, Cloud download will require a solid internet connection, with Windows using at least 4 GB of data. Now, click on the option you want to reinstall Windows on your machine. Here, we’re choosing the ‘Cloud download’ option.

Note: None of the reinstalling options would require using any external installation media.

8 – You will be informed of the current settings for resetting the PC. If you want to change any of the settings, click the ‘Change settings’ option.

9 – On the ‘Choose settings’ window, there are three options for changing the settings. So let’s get started to improve your machine’s performance:

Clean Data? – This option is often used when you wish to give away your PC and do not want anybody else to be able to retrieve your files. That is if that is the case. Toggle the switch to the ‘Yes’ position.
Delete Files From All Drives? – As the name implies, this option allows you to enable whether you want to remove data from your Windows installed disk or wipe all drives clean. Switch to the ‘Yes’ position to erase files from all drives. Also, if enabled, ‘Clean data’ will apply to all drives.
Download Windows? – This option allows you to change from ‘Cloud download’ to ‘Local reinstall’ if you need to change the reinstallation process before starting.

10 – Once you’ve toggled the other settings to your liking, click the ‘Confirm’ button to proceed. Have we activated the ‘Clean data? Option here.

11 – Now, from the bottom section of the window, click the ‘Next’ button.

12 – Windows may take some time to load the following screen. Hold your breath as the process proceeds in the background.

13 – Next, Windows will list the consequences of resetting your PC. After reading them, click the ‘Reset’ button to begin the resetting process on your machine.
