推荐答案

首先，如果你在这台电脑上安装了.net framework 4.5.2，请检查一下可以

通过查看注册表找到.NET Framework版本：

Firstly, please check it if you have installed .net framework 4.5.2 on this pc, you can find .NET Framework versions by viewing the registry:

1.在"开始"菜单中，选择"运行"。

1.On the Start menu, choose Run.

2 。在"打开"框中，输入regedit.exe。

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

您必须具有管理凭据才能运行regedit.exe。

You must have administrative credentials to run regedit.exe.

3.在注册表编辑器中，打开以下子项：

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

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full

请注意，Full子项的路径包括子项Net Framework而不是。 NET Framework。

Note that the path to the Full subkey includes the subkey Net Framework rather than .NET Framework.

检查名为Release的DWORD值。 Release DWORD的存在表明.NET Framework 4.5或更新版本已安装在该计算机上。

Check for a DWORD value named Release. The existence of the Release DWORD indicates that the .NET Framework 4.5 or newer has been installed on that computer.

Release DWORD的值表示安装了哪个版本的.NET Framework。

The value of the Release DWORD indicates which version of the .NET Framework is installed.
