首先介紹下，HM NIS Edit工具，是一款已非常簡潔好用的winform打包工具，功能強大，外掛豐富,還有豐富的第三方介面庫支援。

隨著C/S模式開發的越來越少，這方面的資料，尤其是NSIS的資料都極其稀少。翻了很多文章，進行整合，終於找到比較滿意的.NetFramework檢測，並安裝的實現方式。

進入正題，網上查了很多資料遇到問題：版本號對比一直無效，後來改為了用內建的版本號對比函式。

程式碼如下：

  頭部一定記得新增：!include "WordFunc.nsh"。看名稱就是字串操作之類的。

1.檢測.NetFramework版本(讀取登錄檔，這裡與網上絕大多數資料一樣)

Function GetNetFrameworkVersion

;獲取.Net Framework版本支援

Push $

Push $0

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

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

StrCmp $0 1 KnowNetFrameworkVersion +1

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

ReadRegDWORD $

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

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

2.比較版本，並進行安裝。（網上很多使用If判斷的測試沒有效果,所以使用指令碼內建的版本號比較方法）

Section - "比較版本號"
  DetailPrint "正在檢測安裝環境..."
    Call GetNetFrameworkVersion
    Pop $R1
    ${VersionCompare} "4.5.2" "$R1" $R2
    ${If} $R2 == 0
        DetailPrint "當前版本($R1)，無需安裝元件"
    ${ElseIf} $R2 == 1
        DetailPrint "當前元件版本($R1)過低,需要安裝(4.5.2)版本的元件"
    ${ElseIf} $R2 == 2
        DetailPrint "當前版本($R1)，無需安裝元件"
    ${EndIf}
SectionEnd

Section -.NET
 Call GetNetFrameworkVersion
 Pop $R1
 ${VersionCompare} "4.5.2" $R1 $R2
  ${If} $R2 == 1
   MessageBox MB_ICONINFORMATION|MB_OK "檢測到當前系統缺少微軟.NetFramework 4.5.2元件，需要進行安裝，此操作有可能引起防毒軟體誤報。"
   SetDetailsPrint textonly
   DetailPrint "準備安裝.NetFramework 4.5.2元件"
   SetDetailsPrint listonly
   SetOutPath "$TEMP"
   SetOverwrite on
   File "Src\NETFramework4.5.2.exe"
   ExecWait '$TEMP\NETFramework4.5.2.exe ' $R1
   Delete "$TEMP\NETFramework4.5.2.exe"
  ${EndIf}
SectionEnd

對，就這麼多，把這些貼進去之前的指令碼，就可以搞定。
