使用NSIS检查.NET4.5 +

Question

全部,我知道以下方法来检查NSIS中的框架版本.对于.NET4.0 +我目前使用

Function IsDotNetInstalled

    StrCpy $0 "0"
    StrCpy $1 "SOFTWARE\Microsoft\.NETFramework" ; Registry entry to look in.
    StrCpy $2 0

    StartEnum:
    ; Enumerate the versions installed.
    EnumRegKey $3 HKLM "$1\policy" $2

    ; If we don't find any versions installed, it's not here.
    StrCmp $3 "" noDotNet notEmpty

    ; We found something.
    notEmpty:
        ; Find out if the RegKey starts with 'v'.  
        ; If it doesn't, goto the next key.
        StrCpy $4 $3 1 0
        StrCmp $4 "v" +1 goNext
        StrCpy $4 $3 1 1

        ; It starts with 'v'.  Now check to see how the installed major version
        ; relates to our required major version.
        ; If it's equal check the minor version, if it's greater, 
        ; we found a good RegKey.
        IntCmp $4 ${DOT_MAJOR} +1 goNext yesDotNetReg
        ; Check the minor version.  If it's equal or greater to our requested 
        ; version then we're good.
        StrCpy $4 $3 1 3
        IntCmp $4 ${DOT_MINOR} yesDotNetReg goNext yesDotNetReg

    goNext:
        ; Go to the next RegKey.
        IntOp $2 $2 + 1
        goto StartEnum

    yesDotNetReg:
        ; Now that we've found a good RegKey, let's make sure it's actually
        ; installed by getting the install path and checking to see if the 
        ; mscorlib.dll exists.
        EnumRegValue $2 HKLM "$1\policy\$3" 0
        ; $2 should equal whatever comes after the major and minor versions 
        ; (ie, v1.1.4322)
        StrCmp $2 "" noDotNet
        ReadRegStr $4 HKLM $1 "InstallRoot"
        ; Hopefully the install root isn't empty.
        StrCmp $4 "" noDotNet
        ; Build the actuall directory path to mscorlib.dll.
        StrCpy $4 "$4$3.$2\mscorlib.dll"
        IfFileExists $4 yesDotNet noDotNet

    noDotNet:
        ; No, something went wrong along the way.  Looks like the 
        ; proper .NET Framework isn't installed.  
        MessageBox MB_ICONEXCLAMATION "To install UserCost, Microsoft's .NET Framework v${DOT_MAJOR}.${DOT_MINOR} \
        (or higher) must be installed. Cannot proceed with the installation!"
        ${OpenURL} "${WWW_MS_DOTNET4}"
        Abort

    yesDotNet:
        ; Everything checks out. Proceed with the rest of the installation.

FunctionEnd

这对.NET4.0非常有效,但我现在扩展了我的应用程序以利用async/ awaitfeatures,随后需要用户安装.NET4.5 +.上面的方法不适合,因为.NET4.5的安装现在不使用regestry路径'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\Policy"来存储任何新信息,即该路径似乎没有保存值.NET4.0和4.5之间的变化.现在我看到以下帖子:

带有.NET 4.5的NSIS安装程序

它使用注册表路径/条目'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP'来进行检查.现在这也是机器人工作,因为条目不会从.NET4.0更改为4.5.我注意到有一个名为'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v4.0.30319\SKUs.NETFramework,Version = v4.5'的条目,我可以使用它来检查框架版本吗？

是否有使用NSIS检查.NET4.5的方法的官方线？

谢谢你的时间.

注意:随后我的用户执行的.NET4.5的某些安装具有注册表值

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

命名的DWORD值Release是不是378389,但378181.进行此更改似乎可以解决问题,因为该条目Release不在.NET4.5及更低版本的注册表中.

Answer 1

是的,有一种官方方法可以检查是否安装了.NET Framework 4.5,即使它不是很友好.来自MSDN:

您可以通过HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full在注册表中检查DWORD名为的值的子项来测试是否安装了.NET Framework 4.5或.NET Framework 4 Release.这种情况的存在DWORD表明.NET Framework 4.5已经安装在该计算机上.Release的值是版本号.要确定是否已安装.NET Framework 4.5的最终发行版,请检查是否等于或大于378389.

http://msdn.microsoft.com/en-us/library/hh925568.aspx

这意味着你首先要检查是否安装了4.0,然后检查是否有一个名为Releasein 的值HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full,如果是,那么已经安装了4.5(我想你可以跳过检查预发布版本).

编辑:在这里查看这篇文章有关检测旧安装的.NET版本和此MSDN文章的详细信息,以区分4.5.x版本.

Answer 2

这是我编写的一个函数,它可以检查并在需要时下载.NET 4.5.此外,代码还会查找.NET安装程序的本地副本 - 以防您将安装程序放到CD或USB驱动器上.支持静默和非静默安装,以及设置重新启动标志.该函数是自包含的,但是您希望包含LogicLib(它包含在基本的NSIS安装中).

这是我为Rachel故事书的安装程序编写的代码.

Function CheckAndDownloadDotNet45
# Let's see if the user has the .NET Framework 4.5 installed on their system or not
# Remember: you need Vista SP2 or 7 SP1.  It is built in to Windows 8, and not needed
# In case you're wondering, running this code on Windows 8 will correctly return is_equal
# or is_greater (maybe Microsoft releases .NET 4.5 SP1 for example)

IntCmp $dotNET45IsThere 378389 is_equal is_less is_greater

is_equal:
    Goto done_compare_not_needed

最后，我使用了下面的函数，它利用了上面的答案。此方法首先创建一个"$INSTDIR\dotNETFramework"包含 .NET Web 安装程序的目录：

Function CheckAndInstallDotNet
    ; Installer dotNetFx45_Full_setup.exe avalible from http://msdn.microsoft.com/en-us/library/5a4x27ek.aspx
    ; Magic numbers from http://msdn.microsoft.com/en-us/library/ee942965.aspx
    ClearErrors
    ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full" "Release"
    IfErrors NotDetected
    ${If} $0 >= 378389
        DetailPrint "Microsoft .NET Framework 4.5 is installed ($0)"
    ${Else}
    NotDetected:
        MessageBox MB_YESNO|MB_ICONQUESTION ".NET Framework 4.5+ is required for ProgramX2013, \
            do you want to launch the web installer? This requires a valid internet connection." IDYES InstallDotNet IDNO Cancel 
        Cancel:
            MessageBox MB_ICONEXCLAMATION "To install ProgramX, Microsoft's .NET Framework v${DOT_MAJOR}.${DOT_MINOR} \
                (or higher) must be installed. Cannot proceed with the installation!"
            ${OpenURL} "${WWW_MS_DOTNET4_5}"
            RMDir /r "$INSTDIR" 
            SetOutPath "$PROGRAMFILES"
            RMDir "$INSTDIR" 
            Abort

        ; Install .NET4.5.
        InstallDotNet:
            DetailPrint "Installing Microsoft .NET Framework 4.5"
            SetDetailsPrint listonly
            ExecWait '"$INSTDIR\dotNETFramework\dotNetFx45_Full_setup.exe" /passive /norestart' $0
            ${If} $0 == 3010 
            ${OrIf} $0 == 1641
                DetailPrint "Microsoft .NET Framework 4.5 installer requested reboot."
                SetRebootFlag true 
            ${EndIf}
            SetDetailsPrint lastused
            DetailPrint "Microsoft .NET Framework 4.5 installer returned $0"
    ${EndIf}

    ; Now remove the dotNETFramework directory and contents.
    RMDir /r "$INSTDIR\dotNETFramework" 
FunctionEnd

如果有 Internet 连接，此方法似乎会启动 .NET4.5 安装程序，并在安装完成后返回。

我希望这对其他人有帮助。
