原文 NSIS：判断并安装.NET Framework 4 的例子

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} $R1 < '4.0.30319'
05  SetDetailsPrint textonly
06  DetailPrint "正在安装 .NET Framework 4"
07  SetDetailsPrint listonly
08  
09  SetOutPath "$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，效果可参考紫辰记账本安装程序。
