WSUS-SrvA is running Windows Server 2008 R2 Enterprise and can sync updates.

WSUS-SrvB is running Windows Server 2012 R2 Standard and is on a detached network.

When we run wsusutil.exe export export.xml.gz logfile we receive the error: Fatal Error: The gzip stream cannot contain more than 4GB data

From my investigations on via Google, I found that .NET 2 had this issue and the issue was resolved in .NET 4.

We have installed .NET 4 on the server and I have changed the Application Pool for WSUS site in IIS, but I still receive the above error.

Do I need to do something else to switch WSUS to use .NET 4? Or is this something else?

I have installed the update for this as per http://blogs.technet.com/b/wsus/archive/2013/04/09/problem-solved-the-wsus-export-bug.aspx

Further digging, I found that we needed to run wsusutil.exe with .NET4 and the way to do this was as follows:

  1. Create a file named wsusutil.exe.config in C:\Program Files\Update Services\Tools

  2. Edit the file and add the following:

    <configuration><startup><supportedRuntime version="v4.0.30319" /></startup></configuration>

  3. Re-run the wsusutil command and all should be well

I couldn't get the XML to appear correctly, so had to place it all on one line.

Neil, Thank you for posting this information because it is really helpful. If I may add my 2 cents.

In order to verify that you have .Net Framework version 4.0.30319 go to C:\Windows\Microsoft.NET\Framework\v4.0.30319\ OR C:\Windows\Microsoft.NET\Framework64\v4.0.30319\

Search for clr.dll and right click on it then go to Details to find what version or .Net Framework.

  • Since the OP was asking about _how_ to get WSUS using .NET 4, not checking which .NET version is used, your suggestions might be better placed as a comment, rather than as a solution to the original question. – Castaglia Feb 19 '16 at 23:42
