What are mscorlib.tlb Error Messages?


Dynamic Link Library mscorlib.tlb Errors

mscorlib.tlb is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mscorlib.tlb, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Bible Pro) could share the same mscorlib.tlb 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 TLB 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 mscorlib.tlb is attempted to be loaded either when Bible Pro is starting up, or in some cases already running. Some of the most common mscorlib.tlb errors include:

Your mscorlib.tlb file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Bible Pro), or deleted by a malware infection. Furthermore, mscorlib.tlb file corruption could be caused from a power outage when loading Bible Pro, system crash while loading mscorlib.tlb, 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 mscorlib.tlb 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 mscorlib.tlb 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 mscorlib.tlb error, please proceed to the Step 2 below.

Step 2: If recently installed Bible Pro (or related software), uninstall then try reinstalling Bible Pro software.

You can uninstall Bible Pro 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 Bible Pro 14.3 and click "Uninstall"
  5. Follow the prompts for uninstallation.

After the software has been fully uninstalled, restart your PC and reinstall Bible Pro software.

If this Step 2 fails as well, please proceed to the Step 3 below.

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 mscorlib.tlb 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 mscorlib.tlb error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve mscorlib.tlb 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 mscorlib.tlb Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying mscorlib.tlb to your appropriate Windows system directory. BibleOcean typically does not release Bible Pro TLB 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 mscorlib.tlb and all other TLB files for Bible Pro. An incorrectly installed TLB file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
