Method 1: Installing the Cstestglobal.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 "Cstestglobal.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 "Cstestglobal.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 "Cstestglobal.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 "Cstestglobal.dll" file.

   

5. First, we must run the Windows Command Prompt as 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".

   

6. Paste the command below into the Command Line that will open up and hit Enter. This command will delete the damaged registry of the Cstestglobal.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%\System32\regsvr32.exe /u Cstestglobal.dll

   

7. If the Windows you use has 64 Bit architecture, after running the command above, you must run the command below. This command will clean the broken registry of the Cstestglobal.dll file from the 64 Bit architecture (The Cleaning process is only with registries in the Windows Registry Editor. In other words, the dll file that we pasted into the SysWoW64 folder will stay as it is).

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

   

8. 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%\System32\regsvr32.exe /i Cstestglobal.dll

   

9. If you are using a Windows with 64 Bit architecture, after running the previous command, you need to run the command below. By running this command, we will have created a clean registry for the Cstestglobal.dll file (We deleted the damaged registry with the previous command).

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

   

10. If you did the processes in full, the installation should have finished successfully. If you received an error from the command line, you don't need to be anxious. Even if the Cstestglobal.dll file was installed successfully, you can still receive error messages like these due to some incompatibilities. In order to test whether your dll problem was solved or not, try running the software giving the error message again. If the error is continuing, try the 2nd Method to solve this problem.

Method 2: Copying The Cstestglobal.dll File Into The Software File Folder 

In order to install the dll file, you need to find the file folder for the software that was giving you errors such as "Cstestglobal.dll is missing", "Cstestglobal.dll not found" or similar error messages. In order to do that, Right-click the software's shortcut and click the Properties item in the right-click menu that appears.

   

2. Click on the Open File Location button that is found in the Properties window that opens up and choose the folder where the application is installed.

   

3. Copy the Cstestglobal.dll file.
4. Paste the dll file you copied into the software's file folder that we just opened.

   

5. When the dll file is moved to the software file folder, it means that the process is completed. Check to see if the problem was solved by running the software giving the error message again. If you are still receiving the error message, you can complete the 3rd Method as an alternative.
