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:

Function GetNetFrameworkVersion
;获取.Net Framework版本支持
Push $1
Push $0
ReadRegDWORD $0 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv4Full" "Install"
ReadRegDWORD $1 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv4Full" "Version"
StrCmp $0 1 KnowNetFrameworkVersion +1
ReadRegDWORD $0 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv3.5" "Install"
ReadRegDWORD $1 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv3.5" "Version"
StrCmp $0 1 KnowNetFrameworkVersion +1
ReadRegDWORD $0 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv3.0Setup" "InstallSuccess"
ReadRegDWORD $1 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv3.0Setup" "Version"
StrCmp $0 1 KnowNetFrameworkVersion +1
ReadRegDWORD $0 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv2.0.50727" "Install"
ReadRegDWORD $1 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv2.0.50727" "Version"
StrCmp $1 "" +1 +2
StrCpy $1 "2.0.50727.832"
StrCmp $0 1 KnowNetFrameworkVersion +1
ReadRegDWORD $0 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv1.1.4322" "Install"
ReadRegDWORD $1 HKLM "SOFTWAREMicrosoftNET Framework SetupNDPv1.1.4322" "Version"
StrCmp $1 "" +1 +2
StrCpy $1 "1.1.4322.573"
StrCmp $0 1 KnowNetFrameworkVersion +1
ReadRegDWORD $0 HKLM "SOFTWAREMicrosoft.NETFrameworkpolicyv1.0" "Install"
ReadRegDWORD $1 HKLM "SOFTWAREMicrosoft.NETFrameworkpolicyv1.0" "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区段进行.NET静默安装: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.

Section -.NET
Call GetNetFrameworkVersion
Pop $R1
 ${If} $R1 < '4.0.30319'
 SetDetailsPrint textonly
 DetailPrint "正在安装 .NET Framework 4"
 SetDetailsPrint listonly

 SetOutPath "$TEMP"
 SetOverwrite on
 File "dotNetFx40_Full_x86_x64.exe"
 ExecWait '$TEMPdotNetFx40_Full_x86_x64.exe /q /norestart /ChainingPackage FullX64Bootstrapper' $R1
 Delete "$TEMPdotNetFx40_Full_x86_x64.exe"
 ${EndIf}
SectionEnd
