所有，我知道以下方法可以检查 NSIS 中的框架版本.对于 .NET4.0+ 我目前使用

All, I am aware of the following methods to check the framework version in NSIS. For .NET4.0+ I currently use

Function IsDotNetInstalled

    StrCpy $0 "0"
    StrCpy $1 "SOFTWAREMicrosoft.NETFramework" ; Registry entry to look in.
    StrCpy $2 0

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

这对于 .NET4.0 非常有效，但我现在扩展了我的应用程序以利用 async/await 功能，随后需要用户安装 .NET4.5+.上述方法不适合，因为 .NET4.5 的安装现在不使用注册路径HKEY_LOCAL_MACHINESOFTWAREMicrosoft.NETFrameworkPolicy"来存储任何新信息，即该路径似乎不包含一个值.NET4.0 和 4.5 之间的变化.现在我看到了以下帖子:

This works very well for .NET4.0, but I have now extended my application to utilise the async/await features and subsequently need users to install .NET4.5+. The above method is not suitable as the installation for .NET4.5 now does not use the regestry path 'HKEY_LOCAL_MACHINESOFTWAREMicrosoft.NETFrameworkPolicy" to store any new information, that is that path does not seem to hold a value that changes between .NET4.0 and 4.5. Now I have seen the following posts:

带有 .NET 4.5 的 NSIS 安装程序

它使用注册表路径/条目HKEY_LOCAL_MACHINESOFTWAREMicrosoftNET Framework SetupNDP"来进行检查.现在这也可以 bot 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_MACHINESOFTWAREMicrosoft.NETFrameworkv4.0.30319SKUs.NETFramework,Version=v4.5' 的条目，我可以使用它来检查框架版本吗?

which uses the registry path/entry 'HKEY_LOCAL_MACHINESOFTWAREMicrosoftNET Framework SetupNDP' to do the checks. Now this also does bot work as the entry does not change from .NET4.0 to 4.5. I notice that there is and entry called 'HKEY_LOCAL_MACHINESOFTWAREMicrosoft.NETFrameworkv4.0.30319SKUs.NETFramework,Version=v4.5' can I use this to check the Framework version invariably?

是否有使用 NSIS 检查 .NET4.5 的官方方法?

Is there an offical line of the way to check for .NET4.5 using NSIS?

感谢您的时间.

注意:随后我的用户执行的一些 .NET4.5 安装具有

HKEY_LOCAL_MACHINESOFTWAREMicrosoftNET Framework SetupNDPv4Full

名为 Release 的 DWORD 值不是 378389 而是 378181.进行此更改似乎解决了问题，因为 Release 的条目不在 .NET4.5 及以下版本的注册表中.

a DWORD value named Release was not 378389 but 378181. Making this change seemed to resolve the problem as the entry for the Release is not in the registry for .NET4.5 and below.

378389
