Common DLL Errors  -Wab.dll

missing WAB.dll file

This error occurs when attempting to open or use the Windows Address Book. In turn you will be unable to access the features that it offers until you have resolved the problem. There are two likely causes of this problem and both require similar steps to resolve. The Windows Address Book dll, or wab.dll is either missing or has become damaged or corrupt. It may also be possible that you have an incorrect version of the wab.dll library installed on your computer, but again these steps will resolve the issue if this is the cause.

Locate the wab.dll file on your system, and rename it something like wab.old. This will prevent Windows from attempting to access the file it is corrupt and enable you to add a clean and undamaged version. If the file does not exist then proceed with the following steps anyway. Ensure that you are logged on to your computer as an administrator or with administrator privileges and then remove and reinstall Outlook Express. Outlook Express contains the Windows Address Book files, including wab.dll, so this reinstallation will ensure that everything now works correctly.
