You are going to use this utility to tell the operating system to start up in 'Safe mode' Why? Safe mode only loads necessary operating system files. When files are loaded into the operating system, they can be harder and more complicated to fix.To set your computer to boot into safe mode. Click on the 'Boot.ini' tab in Windows XP, or simply the 'Boot' tab in Vista or 7. Select the 'SafeBoot' and 'Networking' options and press 'Apply.' You will be prompted to reboot. Click OK.

However, it is wise to scan all protected files to ensure that there are not multiple issues.
4. Monitor the command prompt window. In some, but not all cases, you may be prompted to insert your Windows install CD in order to complete the repair. If this happens to you, simply insert the CD into your drive and press the 'Retry' button.
5. Close the command prompt once the file checker has finished. You now need to set your computer to boot back up normally. Go back to the 'Msconfig' utility and uncheck the 'SafeBoot' and 'Networking' options. After that, you are safe to reboot your computer, and your dll libraries should be free of errors.

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. Another common issue is “Page fault in non-paged area,” which may point to corrupted data on your hard drive or failing memory modules. If any specific hardware driver is mentioned, note this as well.
2. Shut down the computer and unplug its power cable from the wall. Press and hold the power button for a few seconds to discharge any residual power from the motherboard. Let the system sit for 10 minutes. Minor power surges sometimes cause a BSOD, and letting the circuits discharge for a few minutes may resolve the problem.

3. Plug the power cables back in, and reboot the computer. Tap 'F8' repeatedly until you get to the Windows boot option menu. Select “Safe Mode” and press “Enter.”
4. Log in using an administrator account and password.
5. Uninstall any recently added hardware or software if the BSOD occurred soon thereafter.
6. Click the Windows 'Start' button, select “Run,” type “eventvwr” (without quotation marks here and throughout) and press “Enter.”
7. Click “System” and click the “Source” column header to arrange the items in that category in alphabetical order.
8. Look for any errors or warnings under the source “disk.” If you see any, your hard drive may be failing.
9. Click the Windows 'Start' button, select “Run,” type “cmd” and press “Enter” to bring up a command prompt window.
10. Type 'chkdsk /r' and press “Enter:”
11. Press “Y,” press “Enter,” type “exit” and press 'Enter' to close the window.
12. Reboot your computer and allow the Check Disk utility to run. This Windows utility checks your hard drive for errors and repairs bad sectors and file system errors. This process may take an hour or more.
13. Log in to Windows using an administrator account.
14. Click the Windows 'Start' button, select “Run,” type “eventvwr” and press “Enter.” Click the “Application” log.
15. Click “Time” to arrange the items in chronological order, beginning with the most recent.
16. Double-click the most recent log that lists “Winlogon” as its source. This is your Check Disk report.
17. Review the information in the Description field. If the log notes any bad sectors, consider replacing your hard drive as soon as possible, even if Check Disk was able to repair them. Bad sectors sometimes are symptoms of an impending hard drive failure.

At the Command Prompt, type 'C:' and press 'Enter.' The Command Prompt will change to 'C:\Windows\system32>.' (If the operating system is installed on a drive other than the C drive, substitute the operating system's drive letter in the previous command in place of 'C.')
5. Type 'chkdsk /f' and press 'Enter' at the 'C:\Windows\system32>' prompt to run Chkdsk to repair file system errors. The '/f' switch will cause Chkdsk to fix any file system errors it discovers. Chkdsk will sequentially verify files, indexes and list errors found and will repair the file system in a series of steps. A summary will be presented when the check is complete. The next prompt will be 'C:\Windows\system32>.'
6. Type 'chkdsk /r' and press 'Enter' at the 'C:\Windows\system32>' prompt to run Chkdsk to recover bad hard drive sectors.

If any bad sectors were found in Step 6 and repaired, no bad sectors should be found in this check. If bad sectors are found again, the hard drive is showing signs that it is beginning to fail. Back up data on that hard drive as soon as possible, as the hard drive may be near the end of its life.
