Stop downloading Keygens, prefer Open Source code!

Here is a recap (again) of the long discussion process posted here, a Big thank you to those who explained the procedures, really thank you!

Remember that there have been changes over the versions, so if you want to understand the main points and anticipate future changes, reread the discussions, get your hands/fingers in!

Also remember to stop the updates.

And if the software is useful to you, consider purchasing it to support the developers behind it.


First Step:

Download DnSpy v6.1.8 win64bit (12.07.2020) (https://dnspy.org/) - A powerful open-source .NET debugging*

Close/Quit Netlimiter (NLClientApp.exe -> Task Manager - Details)
and
Stop the associated service NetLimiter Service (nlsvc.exe -> Task Manager - Services)

Open DnSpy.exe v6.1.8 win64bit (12.07.2020) as Administrator.
In DnSpy menu - Open the Netlimiter.dll file in its original installation/location (because the library is linked to other dlls) - Remember to make a copy/backup of this file, in case of mishandling.


First Change:

In Explore Assembly window:
plan summary: NetLimiter (version) => NetLimiter.dll => {} NetLimiter.Service => NLLicense -> NLLicense()
Expand Netlimiter (5.3.26), then Netlimiter.dll
Expand Netlimiter.Service
Expand NLLicense
Select NLLicense()

Right click on the code window -> "Edit this method C#"
(Or Left click on the code window -> Ctrl+Shift+E)

Replace:
this.IsRegistered = false; -> this.IsRegistered = true;

Click on Compile


Second Change:

In Explore Assembly window:
plan summary: NetLimiter (version) => NetLimiter.dll => {} NetLimiter.Service => NLServiceTemp -> InitLicense ()
Expand Netlimiter (5.3.26), then Netlimiter.dll
Expand Netlimiter.Service
Expand NLServiceTemp
Select InitLicense ()

Right click on the code window -> "Edit this method C#"
(Or Left click on the code window -> Ctrl+Shift+E)

Replace:
DateTime expiration = installTime.AddDays(28.0);
->
DateTime expiration = installTime.AddDays(99999.0);

Important - To avoid System.Exception error:
(In the same code window - Line 43)

Replace:
catch (Exception exception)
->
catch (System.Exception exception)

Replace here:

		catch (Exception exception)
		{
			regData = null;
			NLServiceTemp._logger.LogError(exception, "Failed to init existing license: {path}", new object[]
			{
				licensePath
			});
		}

->

		catch (System.Exception exception)
		{
			regData = null;
			NLServiceTemp._logger.LogError(exception, "Failed to init existing license: {path}", new object[]
			{
				licensePath
			});
		}

Click on Compile

If you want to do what is optional before finishing, do it! (You can do it later or after too)

In DnSpy, Menu - File -> Save All (or Ctrl+Shift+S) -> Click OK

Restart Netlimiter (NLClientApp.exe) and NetLimiter Service (nlsvc.exe)


Update ?

This works for version 5.3.25 and 5.3.26 (you can keep the same file for 5.3.26) but be aware that there may be future changes.

Most of the mistakes some people make are forgetting this -> Open the Netlimiter.dll file in its original installation/location (because the library is linked to other dlls)

Or sometimes this -> Stop the associated service NetLimiter Service (nlsvc.exe -> Task Manager - Services)


OPTIONAL: Change Registration Name

In Explore Assembly window:
plan summary: NetLimiter (version) => NetLimiter.dll => {} NetLimiter.Service => NLLicense => RegName ->get_RegName
Expand Netlimiter (5.3.26), then Netlimiter.dll
Expand Netlimiter.Service
Expand NLLicense
Expand RegName
Select get_RegName

Right click on the code window -> "Edit this method C#"
(Or Left click on the code window -> Ctrl+Shift+E)

Replace:
return this.<RegName>k__BackingField; -> return "YOURNAMEHERE";
(Example -> return "KupBE";)

Click on Compile

In DnSpy, Menu - File -> Save All (or Ctrl+Shift+S) -> Click OK

请停止下载密钥生成工具,更喜欢使用开源代码吧!
以下是这次漫长讨论过程的总结(再次)。非常感谢那些解释相关流程的人,真心谢谢你们!
请记住,各个版本之间确实发生了一些变化。因此,如果你想理解主要的内容并预见未来的变化,建议重新阅读相关的讨论内容,亲自尝试操作一下吧!
同时,记得停止这些更新操作。
如果这款软件对你有帮助,那么请考虑购买它,以支持其开发者。

第一步:

下载 DnSpy v6.1.8 win64bit 版本(发布日期:2020 年 7 月 12 日),下载链接:https://dnspy.org/——一款强大的开源 .NET 调试工具。
关闭/退出 Netlimiter 程序(NLClientApp.exe -> 任务管理器 - 详细信息)以及相关的 NetLimiter 服务(nlsvc.exe -> 任务管理器 - 服务列表)
以管理员权限打开 DnSpy.exe v6.1.8 win64bit(版本:12.07.2020)。在 DnSpy 程序中,选择“打开 Netlimiter.dll 文件”选项,将其放置在原始的安装位置(因为该库与其他 DLL 文件有链接关系)。记得在出错的情况下,备份这个文件以防万一。

第一个变化:

在“探索汇编”窗口中:计划摘要如下: NetLimiter (version) => NetLimiter.dll => {} NetLimiter.Service => NLLicense -> NLLicense() 展开 Netlimiter(5.3.26),然后展开 Netlimiter.dll、Netlimiter.Service,最后选择 NLLicense。
在代码窗口上右键点击 -> 选择“编辑此方法 C#”选项(或者左键点击代码窗口后按 Ctrl+Shift+E 组合键)
替换: this.IsRegistered = false; 改为 this.IsRegistered = true;
点击“编译”按钮

第二次变化:

在“探索汇编”窗口中:计划摘要如下: NetLimiter (version) => NetLimiter.dll => {} NetLimiter.Service => NLServiceTemp -> InitLicense () 展开 Netlimiter(5.3.26),然后展开 Netlimiter.dll、Netlimiter.Service 以及 NLServiceTemp。选择 InitLicense()。
在代码窗口上右键点击 -> 选择“编辑此方法 C#”选项(或者左键点击代码窗口后按 Ctrl+Shift+E 组合键)
替换: DateTime expiration = installTime.AddDays(28.0); 改为 DateTime expiration = installTime.AddDays(99999.0);
重要提示——为了避免出现 System.Exception 错误,请确保在同一代码窗口的第 43 行进行操作。
替换: catch (Exception exception) 改为 catch (System.Exception exception)
在此处替换:

		catch (Exception exception)
		{
			regData = null;
			NLServiceTemp._logger.LogError(exception, "Failed to init existing license: {path}", new object[]
			{
				licensePath
			});
		}

->

		catch (System.Exception exception)
		{
			regData = null;
			NLServiceTemp._logger.LogError(exception, "Failed to init existing license: {path}", new object[]
			{
				licensePath
			});
		}

点击“编译”按钮
如果你希望在完成之前先做一些可选的事情,那就去做吧!(你也可以稍后或者之后再做这件事。)
在 DnSpy 中,点击菜单→文件→保存所有文件(或按 Ctrl+Shift+S 键)→点击确定。
重新启动 Netlimiter(NLClientApp.exe)和 NetLimiter 服务(nlsvc.exe)

有更新吗?

这一方法适用于版本 5.3.25 和 5.3.26。你可以保留相同的文件用于 5.3.26 版本。不过请注意,未来可能会有一些更改。
大多数人犯的错误之一就是忘记这一点——即应该打开位于原始安装路径下的 Netlimiter.dll 文件(因为该库与其他一些 DLL 文件是相互链接的)。
或者有时候,需要停止相关的服务 NetLimiter Service(nlsvc.exe -> 任务管理器 - 服务)。

可选:更改注册名称

在“探索汇编”窗口中:计划摘要如下: NetLimiter (version) => NetLimiter.dll => {} NetLimiter.Service => NLLicense => RegName ->get_RegName 展开 Netlimiter(5.3.26),然后展开 Netlimiter.dll、Netlimiter.Service、NLLicense 以及 RegName 模块。选择 get_RegName 模块。
在代码窗口上右键点击 -> 选择“编辑此方法 C#”选项(或者左键点击代码窗口后按 Ctrl+Shift+E 组合键)
替换: return this.<RegName>k__BackingField; 变为 return "YOURNAMEHERE"; (例如: return "KupBE";
点击“编译”按钮
在 DnSpy 中,点击菜单→文件→保存所有文件(或按 Ctrl+Shift+S 键)→确认。

仍然有效,日期:2026 年 8 月 14 日

5.3.27.0 OK
