How to Sort Dll Problems on Vista

Instructions
1. Go to 'Start' on your taskbar and select 'Run.' A pop=up window will appear to open the 'Run' tool. Type the letters 'cmd' in the search box and press 'OK.'
2. Look for the DLL file name in the search results listing and examine the file path for the DLL file. Most DLL files on Windows Vista are located in the file path: 'C:\Windows\System32' or sometimes in the subfolder, 'C:\Documents and Settings.'
3. Unregister the DLL file from the directory. Type 'regsvr32 /u C:\filepath\DLL_filename' in the command prompt. The text 'filepath' and 'DLL_filename' are shown as placeholders and you should substitute this information with a specific file path and DLL file name that you want to unregister.
4. Press the 'Enter' key after typing the command. This will unregister and delete the DLL file from the Windows file registry. Avoid deleting system or shared DLL files that may be used by other programs. Your computer could crash, and you may lose important data. Make sure that you back up or rename any DLL files that you plan to unregister and delete from the Windows file registry.
5. Download the latest version of any deleted or missing DLL files from the internet. Reinstall the files onto your computer and copy the DLL files in the file path 'C:\Windows\System32.'
