How to Solve a Rundll Error

1. Download the CCleaner free program (see resources) and install it onto your computer by following the program installation instructions.
2. Run CCleaner by double-clicking on its icon on the desktop.
3. Click the 'Registry' button icon, located on the left side of the program screen. This will cause the 'Registry Integrity' section to open up.
4. Place a check mark in the option box next to 'Missing shared DLL files' and every other box in the 'Registry Integrity' section.
5. Click the 'Scan for Issues' button. CCleaner will start a scan of the registry system for missing or corrupt DLL files.
6. Click the 'Fix Selected Issues' button after the scan has finished.
7. Click the 'Yes' button in the dialog box to back up your registry.
8. Click the 'Fix All Selected Issues' button in the dialog box. Click 'OK' in the next dialog box that pops up. Doing this fixes the missing or corrupt DLL files in addition to any errors connected to these files.
