Method 1: Copying the Msimrt16.dll File to the Windows System Folder 

1. The file you downloaded is a compressed file with the ".zip" extension. In order to install it, first, double-click the ".zip" file and open the file. You will see the file named "Msimrt16.dll" in the window that opens up. This is the file you need to install. Drag this file to the desktop with your mouse's left button.

   

2. Copy the "Msimrt16.dll" file file you extracted.
3. Paste the dll file you copied into the "C:\Windows\System32" folder.

   

4. If your system is 64 Bit, copy the "Msimrt16.dll" file and paste it into "C:\Windows\sysWOW64" folder.

   NOTE! On 64 Bit systems, you must copy the dll file to both the "sysWOW64" and "System32" folders. In other words, both folders need the "Msimrt16.dll" file.

   

5. In order to complete this step, you must run the Command Prompt as administrator. In order to do this, all you have to do is follow the steps below.

   NOTE! We ran the Command Prompt using Windows 10. If you are using Windows 8.1, Windows 8, Windows 7, Windows Vista or Windows XP, you can use the same method to run the Command Prompt as administrator.

   1. Open the Start Menu and before clicking anywhere, type "cmd" on your keyboard. This process will enable you to run a search through the Start Menu. We also typed in "cmd" to bring up the Command Prompt.
   2. Right-click the "Command Prompt" search result that comes up and click the Run as administrator" option.

   

6. Paste the command below into the Command Line window that opens up and press Enter key. This command will delete the problematic registry of the Msimrt16.dll file (Nothing will happen to the file we pasted in the System32 folder, it just deletes the registry from the Windows Registry Editor. The file we pasted in the System32 folder will not be damaged).

   %windir%\System32\regsvr32.exe /u Msimrt16.dll

   

7. If you are using a 64 Bit operating system, after doing the commands above, you also need to run the command below. With this command, we will also delete the Msimrt16.dll file's damaged registry for 64 Bit (The deleting process will be only for the registries in Regedit. In other words, the dll file you pasted into the SysWoW64 folder will not be damaged at all).

   %windir%\SysWoW64\regsvr32.exe /u Msimrt16.dll

   

8. We need to make a new registry for the dll file in place of the one we deleted from the Windows Registry Editor. In order to do this process, copy the command below and after pasting it in the Command Line, press Enter.

   %windir%\System32\regsvr32.exe /i Msimrt16.dll

   

9. If the Windows version you use has 64 Bit architecture, after running the command above, you must run the command below. With this command, you will create a clean registry for the problematic registry of the Msimrt16.dll file that we deleted.

   %windir%\SysWoW64\regsvr32.exe /i Msimrt16.dll

   

10. If you did all the processes correctly, the missing dll file will have been installed. You may have made some mistakes when running the Command Line processes. Generally, these errors will not prevent the Msimrt16.dll file from being installed. In other words, the installation will be completed, but it may give an error due to some incompatibility issues. You can try running the program that was giving you this dll file error after restarting your computer. If you are still getting the dll file error when running the program, please try the 2nd method.
