Question

我从以下网址下载了.NET离线安装程序：http://go.microsoft.com/fwlink/?LinkId=852107

如果以前没有安装过，请如何安装.NET 4.7.1？我跑的原因是：

NDP471-KB4033342-x86-x64-AllOS-ENU.exe /passive

虽然我已经在我的计算机上安装了.NET 4.7.1，但它尝试安装它。这个工具有一个帮助开关，但没有一个命令似乎符合我的需要：

---------------------------
Microsoft .NET Framework
---------------------------
Usage:      Setup [switches] 

        All switches are optional. 



/CEIPconsent - Optionally send anonymous feedback to improve the customer experience. 

/chainingpackage <name> - Optionally record the name of a package chaining this one. 

/createlayout <full path> - Download all files and associated resources to the specified location. Perform no other action.  * Disabled * 

/lcid - Set the display language to be used by this program, if possible. Example: /lcid 1031 

/log <file | folder> - Location of the log file. Default is the process temporary folder with a name based on the package. 

/msioptions - Specify options to be passed for .msi and .msp items. Example: /msioptions "PROPERTY1='Value'" 

/norestart - If the operation requires a reboot to complete, Setup should neither prompt nor cause a reboot. 

/passive - Shows progress bar advancing but requires no user interaction. 

/showfinalerror - Passive mode only: shows final page if the install is not successful. 

/showrmui - Passive mode only: shows restart manager dialog if files are in use. 

/pipe <name> - Optionally create a communication channel to allow a chaining package to get progress. 

/promptrestart - If the operation requires a reboot to complete, Setup should prompt, and trigger it if the user agrees. 

/q - Quiet mode, no user input required or output shown. 

/repair - Repair the payloads. 

/serialdownload - Force install operation to happen only after all the payload is downloaded. 

/uninstall - Uninstall the payloads. 

/parameterfolder <full path> - Specifies the path to the Setup’s configuration and data files. 

/NoSetupVersionCheck - Do not check ParameterInfo.xml for setup version conflicts. 

/uninstallpatch {patch code} - Removes update for all products the patch has been applied to. 

/? - Display this help.



Examples:



Silently install the package and create log file SP123.htm in the temp folder:  Setup /q /log %temp%\SP123.htm

Install with no user interaction unless reboot is needed to complete the operation: Setup /passive /promptrestart



Some command line switches are disabled for this package: createlayout

虽然这并没有回答您的问题，但它可能对您或未来的读者有用。

这是一个未经测试的批处理文件，旨在通过阅读注册表来确定.Net Framework的已安装版本：

@Echo Off
SetLocal EnableDelayedExpansion
Set "rk=HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP"
Set/A "vi=ri=0"

For /F "Tokens=3*" %%A In ('Reg Query "%rk%" /F v /K') Do If "%%B"=="" (
    If Not "%%~xA"=="" (Set/A "vi+=1"
        For /F "Tokens=2*" %%C In (
            'Reg Query "%rk%\%%~nxA" /V Version 2^>Nul^|Find /V "\"'
        ) Do Set "_v!vi!=%%D"
    ) Else (Set/A "ri+=1"
        For /F "Tokens=2*" %%E In (
            'Reg Query "%rk%\%%~nxA\Full" /V Release 2^>Nul^|Find /V "\"'
        ) Do Set/A "_r!ri!=%%F"))
If %ri% Gtr 0 (Set/A "vi+=1"
    For /F "Tokens=2" %%A In ('FindStr/B "!_r%ri%!" "%~f0"'
    ) Do Set "_v%vi%=%%A") 

If %vi% Gtr 0 For /F "Tokens=1* Delims==" %%A In ('Set _v') Do Echo([%%B]

未来Release dWord值可以按照相同的格式添加到表格底部：＆＃39; dWordValue SPACE .NETVersion＆＃39;

仅在未安装的情况下安装.NET Framework
