简介: Cannot find a valid license key for ISIS Professional on this computer . this license Manager report

一、报错及报错原因

卸掉proteus再安装时的许可证还是默认的原来,导致安装之后会出现cannot find vaild licence key for I SIS Professional on。


报错:Cannot find a valid license key for ISIS Professional on this computer . this license Manager reported “Bad Product Key”Please ensure that you have installed your licence keys as per the installation instructions. you can run LICENCE.EXE to view the currently installed keys


有道翻译:在这台计算机上找不到ISIS专业版的有效许可密钥。此许可证管理器报告了“坏产品密钥”,请确保您已按照安装说明安装了许可证密钥。您可以运行license . exe来查看当前安装的密钥


二、解决办法

1. 使用运行命令:按下键盘上的“Win + R”组合键,打开“运行”对话框。在对话框中输入“regedit”,然后点击“确定”按钮,即可打开注册表编辑器。




2.运行“编辑→查找”命令打开“查找”窗口,选择“项、值、数据”三个选项,再在“查找目标”中输入proteus,单击“查找”按钮进行查找.




3.如果找到相关项,直接将其删除。接着再按“F3”键继续查找,直至将整个注册表搜索完毕为止,最后重新启动系统应该可以解决问题。[注:一定要一直按“F3”继续查找]




4.要完全卸载并同时删除注册表项,运行中输入:“regedit”,打开“HKEY_LOCAL_MACHINE\SOFTWARE\找到“Labcenter Electronics” 【注:建议直接输入地址搜索】


5.删除掉Labcenter Electronics项,再进行安装。
