What are dte80.olb Error Messages?


Dynamic Link Library dte80.olb Errors

dte80.olb is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like dte80.olb, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like wisptis.exe - to follow. These files were created so that multiple programs (eg. Microsoft Office Basic 2007) could share the same dte80.olb file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared OLB file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when dte80.olb is attempted to be loaded either when Microsoft Office Basic 2007 is starting up, or in some cases already running. Some of the most common dte80.olb errors include:

Your dte80.olb file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Office Basic 2007), or deleted by a malware infection. Furthermore, dte80.olb file corruption could be caused from a power outage when loading Microsoft Office Basic 2007, system crash while loading dte80.olb, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.



How to Fix dte80.olb Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your dte80.olb issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the dte80.olb error, please proceed to the Step 2 below.

Step 2: If recently installed Microsoft Office Basic 2007 (or related software), uninstall then try reinstalling Microsoft Office Basic 2007 software.

You can uninstall Microsoft Office Basic 2007 software by following these instructions (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. In the search box, type "Uninstall" and press "ENTER".
  3. In the search results, find and click "Add or Remove Programs"
  4. Find the entry for Microsoft Office Basic 2007 11 and click "Uninstall"

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many dte80.olb error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the dte80.olb error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your dte80.olb File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate dte80.olb file version. We maintain a comprehensive database of 100% malware-free dte80.olb files for every applicable version of Microsoft Office Basic 2007. Please follow the steps below to download and properly replace you file:

  2. Click the appropriate "Download Now" button and download your Windows file version.
  3. Copy this file to the appropriate Microsoft Office Basic 2007 folder location:
    Windows Vista: C:\Program Files (x86)\Common Files\microsoft shared\MSEnv\
    Windows 10: C:\Program Files (x86)\Common Files\microsoft shared\MSEnv\
    Windows 10: C:\Program Files (x86)\Common Files\microsoft shared\MSEnv\
    Windows 10: C:\Program Files (x86)\Common Files\microsoft shared\MSEnv\
  4. Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.


GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve dte80.olb problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.



Download dte80.olb Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying dte80.olb to your appropriate Windows system directory. Microsoft typically does not release Microsoft Office Basic 2007 OLB files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing dte80.olb and all other OLB files for Microsoft Office Basic 2007. An incorrectly installed OLB file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
