C：、WINDOWS、System32\spool\drtvers\w32x86\3\cnmsm7s.dll时出错拒绝访问

Posted 2023-05-04

按照2889358的回答，试了一下，在注册regsvr32 msjava.dll
后，弹出Loadlibrary("msjava.dll")失败-找不到指定的模块。这个对话框，又应该如何解决呢？谢谢大虾们了

参考技术A 1. 开始-运行窗口，输入“regsvr32 actxprxy.dll”回车，接着会出现一个信息对话 框“DllRegisterServer in
actxprxy.dll
succeeded”，确定。再依次运行以下命令。（这个方法有人说没必要，但重新注册一下那些.dll对系统也没有坏处，反正多方下手，能解决问题就行。）

regsvr32 shdocvw.dll

regsvr32 oleaut32.dll

regsvr32 actxprxy.dll

regsvr32 mshtml.dll

regsvr32 msjava.dll

regsvr32 browseui.dll

regsvr32 urlmon.dll
2.打开注册表(开始－运行－输入regedit)，点编辑－查找－输入cnmsm7s。dll试试。有直接删除就可以了。

用C＃实现Des加密和解密
