检查与NSIS .NET4.5 + [英] Check for .NET4.5+ with NSIS

问题描述

所有的，我知道下面的方法来检查框架版本NSIS。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 "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

这非常适用于.NET4.0，但现在我已延长我的应用程序能够利用异步 / 等待的功能，随后需要用户安装.NET4.5 +。上述方法不适合作为安装为.NET4.5现在不使用regestry路径HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft.NETFramework \策略来存储任何新的信息，即该路径似乎没有持有的值。.NET4.0和4.5之间变化，现在我已经看到了以下职位：

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_MACHINE\SOFTWARE\Microsoft.NETFramework\Policy" 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:

NSIS安装程序与.NET 4.5

，它使用注册表路径/项HKEY_LOCAL_MACHINE \ SOFTWARE \微软\ NET Framework安装\新民主党做检查。现在，这个也做机器人工作的条目不改变从.NET4.0至4.5。我注意到，有和进入所谓的HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft.NETFramework \ v4.0.30319 \ SKUs.NETFramework，版本= V4.5我可以用它来总是检查Framework版本？

which uses the registry path/entry 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP' 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_MACHINE\SOFTWARE\Microsoft.NETFramework\v4.0.30319\SKUs.NETFramework,Version=v4.5' can I use this to check the Framework version invariably?

时的全过程中的一个官方线采用NSIS检查.NET4.5？

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

感谢您的时间。

注：随后一些安装.NET4.5我的用户已经进行有针对的注册表值的

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

的发布 DWORD值不是 378389 ，但 378181 。此更改似乎解决问题作为发布的项目不是在注册表中.NET4.5及以下。的

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.

推荐答案

是有一个的官方的方式来检查是否安装了.NET Framework 4.5，即使它不是一个真正的友好。从 MSDN ：

Yes there is an official way to check if .NET Framework 4.5 is installed, even if it's not really friendly. From MSDN:

您可以测试是否在.NET Framework 4.5或.NET Framework 4通过检查 HKEY_LOCAL_MACHINE \ SOFTWARE \微软\ NET Framework安装\新民主党\ V4 \全部子项在注册表中名为 DWORD 值发布。这个 DWORD 的存在表明，在.NET Framework 4.5已经安装在该计算机上。推出的值是一个版本号。要确定是否安装了.NET Framework 4.5的最终发行版本，检查一个值等于或大于378389。

You can test whether the .NET Framework 4.5 or the .NET Framework 4 is installed by checking the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full subkey in the registry for a DWORD value named Release. The existence of this DWORD indicates that the .NET Framework 4.5 has been installed on that computer. The value of Release is a version number. To determine if the final release version of the .NET Framework 4.5 is installed, check for a value that is equal to or greater than 378389.

这意味着你首先要检查，如果4.0安装，然后检查是否有发布在 HKEY_LOCAL_MACHINE \ SOFTWARE \微软命名的值\ NET Framework安装\新民主党\ V4 \全部，如果是的话，4.5已经安装了（我想你可以跳过检查为pre-发布版本）。

It means you first have to check if 4.0 is installed and then to check if there is a value named Release in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full, if so then 4.5 is already installed (I think you can skip the check for a pre-release version).
