You install a software update for the .NET Framework that uninstalls previously installed software updates for the .NET Framework

SUMMARY

Consider the following scenario. You install a software update for the Microsoft .NET Framework on a computer that is running previously installed software updates for the .NET Framework. The previously installed software updates include the same files as the new software update that you will install. When you install the new software update, the files for the previously installed software updates are removed and are replaced by the files of the new software update.

Note Microsoft software updates are cumulative. This means that each new software update includes the fixes that were included in prior software updates.

SYMPTOMS

If you remove the new software update for the .NET Framework, the remaining files will be the unpatched files of the version of the .NET Framework that you originally installed. Because these files have not been updated, any problems that were resolved by any previously installed software updates for the .NET Framework will occur again.

RESOLUTION

Before you install a software update, we recommend that you open Add/Remove Programs in Control Panel. Note the software updates for the .NET Framework that are currently installed. After you have installed the new software update, open Add/Remove Programs in Control Panel again. Determine the software updates for the .NET Framework that are no longer listed. The software updates that are no longer listed are the software updates that you must reinstall. Remove the new software update. Then, obtain and reinstall the previously installed software updates.

STATUS

This behavior is by design.

MORE INFORMATION

The following example shows how this behavior may occur when you install a software update for the Microsoft .NET Framework 1.1.

Note This behavior may also occur when you install a software update for the Microsoft .NET Framework 1.0.
  1. You currently have the Microsoft .NET Framework 1.1 Service Pack 1 (SP1) installed on the computer. The version of the Mscorwks.dll file on the computer is version 1.1.4322.2032.
  2. You install hotfix 890929. When you do this, the Mscorwks.dll file on the computer is updated from version 1.1.4322.2032 to version 1.1.4322.2052.
  3. You install hotfix 894092. When you do this, the Mscorwks.dll file on the computer is updated from version 1.1.4322.2052 to version 1.1.4322.2323.
  4. You remove hotfix 894092. When you do this, the Mscorwks.dll file that is on the computer reverts back to version 1.1.4322.2032. This version is the version of the Mscorwks.dll file that was on the computer before you installed hotfix 890929.

Community Feedback System

Very often, it takes hours to solve a problem. Very often, you've looked high and low, and have tried a lot of solutions. When you finally found it, chances are, it was because someone else helped you. Here's your chance to give back. Use our community feedback tool to let others know what worked for you and what didn't.

Please also understand that the community feedback system is not warranted to be correct, it's simply a system that we've built to let people try and help each other. If something in a feedback response doesn't make sense to you, or you're not comfortable making changes that the feedback talks about (like registry edits), please consult a professional.

Thank you for using kbAlertz.com Feedback System.
