Fix Acrobat 10.1.3 Runtime Errors When Opening PDFs in Internet Explorer
Question details
Users experience a Microsoft Visual C++ Runtime Library error that forces the application to close when trying to view a PDF.

- Product
- Adobe Acrobat 10.1.3
- Device & OS
- Windows 7
- Scenario
- Opening PDF files directly within the Internet Explorer 9 browser after updating Acrobat to version 10.1.3.
- Observed behavior
- Triggers a Microsoft Visual C++ Runtime Library error and abruptly closes the application.
Ensure you have administrative privileges on your Windows computer, as you will need to modify browser add-ons and potentially run an application repair process.
Disable the AVG Toolbar in Internet Explorer
Third-party browser toolbars, particularly the AVG Toolbar, can conflict with the Adobe Acrobat plugin and cause runtime errors.
In many cases, the Microsoft Visual C++ Runtime Library error is triggered by a compatibility issue between the Acrobat browser extension and antivirus toolbars installed in Internet Explorer.
Launch Internet Explorer 9. Click on the gear icon (Tools) in the upper-right corner and select 'Manage add-ons' from the drop-down menu.
Under 'Toolbars and Extensions', find the AVG Toolbar in the list. Select it and click the 'Disable' button at the bottom right.
Close all Internet Explorer windows, restart the browser, and try opening the PDF file again to see if the runtime error is resolved.

Repair the Acrobat Installation
If disabling toolbars does not fix the issue, the Adobe Acrobat installation or its browser plugins might be corrupted.
Try WPS Office for Seamless PDF Viewing

Frequently Asked Questions
Why does Adobe Acrobat crash when opening a PDF in Internet Explorer?
Crashes and runtime errors often occur due to conflicts between the Acrobat browser plugin and third-party extensions, such as antivirus toolbars, or because the Acrobat installation files have become corrupted during an update.
What does the Microsoft Visual C++ Runtime Library error mean?
This error signifies that a software component (in this case, the Acrobat plugin for Internet Explorer) has encountered a severe logic conflict or missing file, preventing it from executing the standard C++ code libraries required to display the document.
How can I view PDFs without using a web browser?
You can avoid browser-related issues entirely by downloading the PDF file to your local hard drive and opening it with a standalone desktop PDF reader, such as WPS Office or Adobe Acrobat.
