Windows 7, 64-bit, 16 GB 1888 MHz RAM.

When launching some program, I get this error:

“Microsoft .NET Framework” error window

Meanwhile, I either cannot open up a web page at all or the web page will have only text and the formats; pictures, etc., are all messed up.

More detailed debug information as follows:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** Exception Text **************

BTW I haven't installed any Windows .NET IDE or anything and this isn't caused by my program, and please rule out of insufficient RAM because this happens when there are 12 GB of available RAM.

  • Windows 7 comes pre-installed with .Net Framework but you would only get this error if you were running a .Net application – Ramhound Jul 17 '17 at 2:36
  • Cross site related: serverfault.com/questions/661476/…. Check the programs you're currently using, there may be a port leak or port exhaustion when an application makes too many outgoing connections in short period without disposing them properly. – Tetsuya Yamamoto Jul 17 '17 at 3:20
  • Hello @Ramhound Can I update to a newer .net framework to solve this? Or stop and start a/several windows service(s) for this? – Matt Cox Jul 17 '17 at 3:51
  • I know nothing about your application. So that question isn't answerable – Ramhound Jul 17 '17 at 12:17
  • Voting to leave open because this is a known issue. See Magicandre's answer. – music2myear Jul 25 '17 at 22:37

This message comes from the application OpenVPNManager where the developer didn't handle the System.Net.Sockets.SocketException in his code.

Create a new issue in the bugtracker so that it can be fixed.
