当我启用Net framework 3.5将安装但未在Windows 10上启用时，我没有收到错误消息。它安装得很好。问题是，当我在'打开/关闭窗口功能'窗口中启用框架3.5时，我检查框并打开安装窗口，说安装已完成，我需要重新启动。我重新启动计算机，但当我返回到Windows功能窗口时，不再检查 framework 3.5的框。

解决方案

您好，

欢迎来到MSDN论坛。

如果已通过以下步骤安装.NET Framework 3.5，则可以检查它：

1.在"开始"菜单上，选择"运行"。

2.在"打开"框中，输入regedit.exe。

您必须具有管理凭据才能运行regedit.exe。

3.在注册表编辑器中，打开以下子项：

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP

已安装的版本列在NDP子项下。版本号存储在Version条目中。对于.NET Framework 4，Version条目位于Client或Full子项（在NDP下）或两个子项下。

此外，您还可以尝试其他方式安装 framework 3.5。

如果问题仍然存在，请随时告诉我。

祝你好运，

when i enable Net framework 3.5 will install but not enable on windows 10 I am not getting an error message thats the thing. It installs fine. The problem is when i go to enable the framework 3.5 in the ‘turn windows features on/off’ window, i check the box and the install window opens, says install is complete and i need to restart. I restart my computer but when i go back to the windows features window, the box for framework 3.5 is no longer checked.

解决方案

Hi,

Welcome to MSDN forum.

You can check it if .NET Framework 3.5 has been installed via the following steps:

1.On the Start menu, choose Run.

2.In the Open box, enter regedit.exe.

You must have administrative credentials to run regedit.exe.

3.In the Registry Editor, open the following subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP

The installed versions are listed under the NDP subkey. The version number is stored in the Version entry. For the .NET Framework 4 the Version entry is under the Client or Full subkey (under NDP), or under both subkeys.

Besides, you can also try the other ways to install framework 3.5.

If the issue persists, feel free to let me know.

Best regards,
