How to Fix Windows Internal Error 2337
1. Download .NET Framework. The most common cause of this error is an issue with the .NET Framework. Obtain the most recent version of the software (version 3.5) from Microsoft's website and save it to your computer.
2. Install .NET Framework. Locate the dotNetFx35setup.exe file you downloaded in the previous step. Double click the icon to launch the program and begin installation. Follow the instructions provided by the program and do not change any of the default options.

3. Restart your computer. After the .NET Framework installation completes, you must restart your computer for the changes to take effect. Click the 'Start' button, select 'Shut Down,' then choose 'Restart' and click 'OK.'
4. Run the error-causing program. If Internal Error 2337 no longer appears, you have solved the problem and can stop here. If the error message still exists, you need to uninstall the software generating the error.
5. Access the Windows 'Control Panel.' If reinstalling the .NET Framework does not solve the problem, you will need to remove the flawed software. Begin by clicking the 'Start' button. Move your mouse up and place the cursor over the 'Settings' option, then select 'Control Panel' from the sub-menu.
6. Launch the utility used to remove programs. If you use the Windows XP operating system, look for the 'Control Panel' tool called 'Add or Remove Programs.' If you use Windows Vista or Windows 7, this tool goes by a different name: 'Programs and Features.' Locate the tool that corresponds to your computer's operating system, then double click on the icon to launch it.
7. Remove the program experiencing the Internal Error 2337. Scroll down the list of programs on your screen until you find the name of the program you want to remove. Right click on the name of the program and choose the 'Uninstall' option. Confirm that you wish to uninstall the software and leave the window open until the removal process completes.
8. Request replacement software from the manufacturer. This step is difficult to outline with certainty because policies and practices vary from one company to another. Generally speaking, contact the company's technical support department by phone or through email and explain your situation. They will most likely require you to return the defective disc before mailing you a replacement. This process typically takes four to six weeks.
9. Install the software from the replacement disc. Follow the directions provided in your software's installation guide. After installing the software and restarting your computer, Internal Error 2337 should no longer appear.

1. When you see a BSOD, look at the third line of text from the top of the screen to determine why your system halted or can't boot up normally. One common reason is an “unmountable boot volume,” which may indicate a problem with your hard disk or the file structure on it.

1. Update your chipset driver. Navigate to the manufacturer's website for either your PC (if you bought it prebuilt) or to the motherboard manufacturer's website. Download and install the driver. Driver software is usually located under the 'Support' page found on many manufacturer's websites. Restart your computer to ensure proper driver installation.
2. Update the software in which the error occurs. Software such as video games are often updated by their developers via patches, which may fix the issue. Navigate to the website of the application and check for updates or patches. Download and install the most recent patches for that software.

3. Lower the amount of physical memory being used by your computer. Close any unnecessary programs such as unused Internet browser windows. Close programs running in the background by right-clicking their icon in your taskbar and clicking 'Exit.' Launch your task manager by pressing the 'Ctrl,' 'Alt' and 'Delete' keys simultaneously. Click on unnecessary tasks. Click 'End Task.' Following these steps will free up physical memory, lowering the chance of encountering the error.
