Method 1: Copying the Lapack.dll File to the Windows System Folderlink

1. The file you are going to download is a compressed file with the '.zip' extension. You cannot directly install the '.zip' file. First, you need to extract the dll file from inside it. So, double-click the file with the '.zip' extension that you downloaded and open the file.
2. You will see the file named 'Lapack.dll' in the window that opens up. This is the file we are going to install. Click the file once with the left mouse button. By doing this you will have chosen the file.
3. Click the 'Extract To' symbol marked in the picture. To extract the dll file, it will want you to choose the desired location. Choose the 'Desktop' location and click 'OK' to extract the file to the desktop. In order to do this, you need to use the Winrar software. If you do not have this software, you can find and download it through a quick search on the Internet.
4. Copy the 'Lapack.dll' file and paste it into the 'C:WindowsSystem32' folder.
5. If your system is 64 Bit, copy the 'Lapack.dll' file and paste it into 'C:WindowssysWOW64' 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 'Lapack.dll' file.

6. First, we must run the Windows Command Promptas an administrator.

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

   1. Open the Start Menu and type in 'cmd', but don't press Enter. Doing this, you will have run a search of your computer through the Start Menu. In other words, typing in 'cmd' we did a search for the Command Prompt.
   2. When you see the 'Command Prompt' option among the search results, push the 'CTRL' + 'SHIFT' + 'ENTER
   ' keys on your keyboard.
   3. A verification window will pop up asking, 'Do you want to run the Command Prompt as with administrative permission?' Approve this action by saying, 'Yes'.
7. Paste the command below into the Command Line that will open up and hit Enter. This command will delete the damaged registry of the Lapack.dll file (It will not delete the file we pasted into the System32 folder; it will delete the registry in Regedit. The file we pasted into the System32 folder will not be damaged).

   %windir%System32regsvr32.exe /u Lapack.dll

8. 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 Lapack.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%SysWoW64regsvr32.exe /u Lapack.dll

9. You must create a new registry for the dll file that you deleted from the registry editor. In order to do this, copy the command below and paste it into the Command Line and hit Enter.

   %windir%System32regsvr32.exe /i Lapack.dll

10. 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 Lapack.dll file that we deleted.

    %windir%SysWoW64regsvr32.exe /i Lapack.dll

11. You may see certain error messages when running the commands from the command line. These errors will not prevent the installation of the Lapack.dll file. In other words, the installation will finish, but it may give some errors because of certain incompatibilities. After restarting your computer, to see if the installation was successful or not, try running the software that was giving the dll error again. If you continue to get the errors when running the software after the installation, you can try the 2nd Method as an alternative.
