[已解决]批处理命令for提取2行后，怎么给每行设变量？

想弄个bat处理Virtualbox安装包

1. 
   
2. @echo off
   
3. REM 获取最新版本号
   
4. wget -N http://download.virtualbox.org/virtualbox/LATEST.TXT
   
5. for /f %%i in (LATEST.TXT) do (set latest=%%i)
   
6. REM 获取最新版本号目录
   
7. echo http://download.virtualbox.org/virtualbox/%latest%  >dl.txt
   
8. REM .vbox-extpack也可直接下载了
   
9. echo http://download.virtualbox.org/virtualbox/%latest%/Oracle_VM_VirtualBox_Extension_Pack-%latest%.vbox-extpack >>dl.txt
   
10. wget -N -i dl.txt
    
11. REM .exe包含小版本号，不能直接下载
    
12. REM 获取exe文件名
    
13. for /f "delims=<,> tokens=3 skip=4" %%i in (index.html) do (echo %%i>>ddd.txt)
    
14. findstr "exe" ddd.txt>dddd.txt
    
15. REM 去除行首空格
    
16. for /f %%i in (dddd.txt) do (set exe=%%i)
    
17. REM 下载exe
    
18. echo http://download.virtualbox.org/virtualbox/%latest%/%exe% >dl.txt
    
19. wget -N -i dl.txt
    
20. REM 解压VirtualBox-Version-Win.exe
    
21. %exe% --extract --path VirtualBox --silent
    
22. REM 解压Oracle_VM_VirtualBox_Extension_Pack-Version.vbox-extpack
    
23. 7z x *.vbox-extpack -oVirtualBox
    
24. 7z x VirtualBox\Oracle_VM_VirtualBox_Extension_Pack-* -oVirtualBox\ExtensionPacks
    
25. for /f "tokens=4" %%i in ('dir VirtualBox\*.msi') do (echo %%i>>a.txt | findstr "msi" a.txt>b.txt)
    
26. for /f "tokens=*" %%i in (b.txt) do (set msi=%%i)
    
27. msiexec /a VirtualBox\%msi%  /qb TARGETDIR="%CD%\VirtualBox\x86"
    
28. msiexec /a VirtualBox\%msi%  /qb TARGETDIR="%CD%\VirtualBox\x64"
    
29. del *.txt *.html
    
30. pause

VirtualBox-4.3.12-93733-Win.exe解压到VirtualBox目录后有3个文件：
common.cab
VirtualBox-4.3.12-r93733-MultiArch_amd64.msi
VirtualBox-4.3.12-r93733-MultiArch_x86.msi
最后一步不会弄了，msiexec两行都是解压x86的msi...
怎么才能分别执行x86和x64？谢谢
