Method 1: Copying the Installinf.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 "Installinf.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 "Installinf.dll" file file you extracted.
3. Paste the dll file you copied into the "C:\Windows\System32" folder.

   

4. If you are using a 64 Bit operating system, copy the "Installinf.dll" file and paste it into the "C:\Windows\sysWOW64" as well.

   NOTE! On Windows operating systems with 64 Bit architecture, the dll file must be in both the "sysWOW64" folder as well as the "System32" folder. In other words, you must copy the "Installinf.dll" file into both folders.

   

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.

6. Let's copy the command below and paste it in the Command Line that comes up, then let's press Enter. This command deletes the Installinf.dll file's problematic registry in the Windows Registry Editor (The file that we copied to the System32 folder does not perform any action with the file, it just deletes the registry in the Windows Registry Editor. The file that we pasted into the System32 folder will not be damaged).

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

   

7. If you have a 64 Bit operating system, after running the command above, you must run the command below. This command will clean the Installinf.dll file's damaged registry in 64 Bit as well (The cleaning process will be in the registries in the Registry Editor< only. In other words, the dll file you paste into the SysWoW64 folder will stay as it).

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

   

8. In order to cleanly recreate the dll file's registry that we deleted, copy the command below and paste it into the Command Line and hit Enter.

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

   

9. Windows 64 Bit users must run the command below after running the previous command. With this command, we will create a clean and good registry for the Installinf.dll file we deleted.

   %windir%\SysWoW64\regsvr32.exe /i Installinf.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 Installinf.dll file from being installed. In other words, the installation will be completed, but it may give an error due to some incompatibility issues.
