1 检测是否有 net 吗

现在.NET开发的软件已经大行其道，但有些操作系统并不符合软件的运行要求，所以，我们需要在安装程序中进行.NET Framework的判断，如果不符合要求就进行静默安装。

首先，我们在Function区段进行当前.NET版本判断：

01 Function GetNetFrameworkVersion

02 ;获取.Net Framework版本支持

03 Push $1

04 Push $0

05 ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full" "Install"

06 ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full" "Version"

07 StrCmp $0 1 KnowNetFrameworkVersion +1

08 ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5" "Install"

09 ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5" "Version"

10 StrCmp $0 1 KnowNetFrameworkVersion +1

11 ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.0\Setup" "InstallSuccess"

12 ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.0\Setup" "Version"

13 StrCmp $0 1 KnowNetFrameworkVersion +1

14 ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v2.0.50727" "Install"

15 ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v2.0.50727" "Version"

16 StrCmp $1 "" +1 +2

17 StrCpy $1 "2.0.50727.832"

18 StrCmp $0 1 KnowNetFrameworkVersion +1

19 ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v1.1.4322" "Install"

20 ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v1.1.4322" "Version"

21 StrCmp $1 "" +1 +2

22 StrCpy $1 "1.1.4322.573"

23 StrCmp $0 1 KnowNetFrameworkVersion +1

24 ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\.NETFramework\policy\v1.0" "Install"

25 ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\.NETFramework\policy\v1.0" "Version"

26 StrCmp $1 "" +1 +2

27 StrCpy $1 "1.0.3705.0"

28 StrCmp $0 1 KnowNetFrameworkVersion +1

29 StrCpy $1 "not .NetFramework"

30 KnowNetFrameworkVersion:

31 Pop $0

32 Exch $1

33 FunctionEnd

然后，在Section区段进行.NET静默安装：

01 Section -.NET

02 Call GetNetFrameworkVersion

03 Pop $R1

04 ${If} $R1 < '4.0.30319'

05 SetDetailsPrint textonly

06 DetailPrint "正在安装 .NET Framework 4"

07 SetDetailsPrint listonly

09 SetOutPath "$TEMP"

10 SetOverwrite on

11 File "dotNetFx40_Full_x86_x64.exe"

12 ExecWait '$TEMP\dotNetFx40_Full_x86_x64.exe /q /norestart /ChainingPackage FullX64Bootstrapper' $R1

13 Delete "$TEMP\dotNetFx40_Full_x86_x64.exe"

14 ${EndIf}

15 SectionEnd

当然，在Section区段可以做到自动在线下载而不把.NET打到安装包中，这样可以减小安装包体积，效果可
