Known issues and additional information about this security update

For more information about installation issues with the Microsoft .NET Framework 4.0, click the following article number to view the article in the Microsoft Knowledge Base:
2436246 Updates for the .NET Framework may not have a fully localized setup experience

Command-line switches for this update

For information about the various command-line switches that are supported by this update, see the Windows Installer command-line switches document.

For more information about Windows Installer, visit the Windows Installer MSDN website.

Restart requirement

This update does not require a system restart after you apply it unless files being updated are locked or in use. However, installing this update will trigger a restart of all Internet Information Services (IIS)-related services, including the IISADMIN, W3SVC, FTP, and SMTP services. This behavior occurs because a base component for the .NET Framework includes instructions for restarting these services. Therefore, every update to the product will execute the same restarting instructions.

Update removal information

To remove this update, use the Add or Remove Programs item in Control Panel.

Update replacement information

The x64 and Itanium based versions of this security update replace the following security update: 
2160841 MS10-077: Vulnerability in the .NET Framework could allow remote code execution

FILE INFORMATION

The English (United States) version of this software update installs files that have the attributes that are listed in the following tables. The dates and times for these files are listed in Coordinated Universal Time (UTC). The dates and times for these files on your local computer are displayed in your local time and with your current daylight saving time (DST) bias. Additionally, the dates and times may change when you perform certain operations on the files.

For all supported x86-based versions of systems
