NSIS：判斷并安裝.NET Framework的例子

現在.NET開發的軟件已經大行其道，但有些操作系統并不符合軟件的運行要求，所以，我們需要在安裝程序中進行.NET Framework的判斷，如果不符合要求就進行靜默安裝。?

首先，我們在Function區段進行當前.NET版本判斷：

Function GetNetFrameworkVersion
;獲取.Net Framework版本,支持
Push $1
Push $0
ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5" "Install"
ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5" "Version"
StrCmp $0 1 KnowNetFrameworkVersion +1
ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.0\Setup" "InstallSuccess"
ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.0\Setup" "Version"
StrCmp $0 1 KnowNetFrameworkVersion +1
ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v2.0.50727" "Install"
ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v2.0.50727" "Version"
StrCmp $1 "" +1 +2
StrCpy $1 "2.0.50727.832"
StrCmp $0 1 KnowNetFrameworkVersion +1
ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v1.1.4322" "Install"
ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\NET Framework Setup\NDP\v1.1.4322" "Version"
StrCmp $1 "" +1 +2
StrCpy $1 "1.1.4322.573"
StrCmp $0 1 KnowNetFrameworkVersion +1
ReadRegDWORD $0 HKLM "SOFTWARE\Microsoft\.NETFramework\policy\v1.0" "Install"
ReadRegDWORD $1 HKLM "SOFTWARE\Microsoft\.NETFramework\policy\v1.0" "Version"
StrCmp $1 "" +1 +2
StrCpy $1 "1.0.3705.0"
StrCmp $0 1 KnowNetFrameworkVersion +1
StrCpy $1 "not .NetFramework"
KnowNetFrameworkVersion:
Pop $0
Exch $1
FunctionEnd

然后，在Section區段進行.NET靜默安裝

Section -.NET
Call GetNetFrameworkVersion
Pop $R1
? ${If} $R1 < '2.0.50727'
? SetDetailsPrint textonly
? DetailPrint "正在安裝 .NET Framework 2.0 SP2..."
? SetDetailsPrint listonly

? SetOutPath "$TEMP"
? SetOverwrite on
? File "NetFx20SP2_x86.exe"
? ExecWait '$TEMP\NetFx20SP2_x86.exe /quiet /norestart' $R1
? Delete "$TEMP\NetFx20SP2_x86.exe"
? ${EndIf}
SectionEnd

當然，在Section區段可以做到自動在線下載而不把.NET打到安裝包中，這樣可以減小安裝包體積，效果可參考紫辰記賬本安裝程序。
