NSIS：判断并安装.NET Framework 4 的例子

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。
