Problem in Register DLL in XP machine

HI All,
I am using below code in Batch file to register my dll using regasm, it is working fine in Window 7 but not working for window XP.
Can anybody help me in finding solution so that installer works for both XP and Window 7 both. the installer is for 64bit machine

echo on

Set RegQry=HKLM\Hardware\Description\System\CentralProcessor\0
 
REG.exe Query %RegQry% > checkOS.txt
 
Find /i "x86" < CheckOS.txt > StringCheck.txt

If %ERRORLEVEL% == 0 (

cd C:\Windows\Microsoft.NET\Framework\v4.0.30319
regasm -u "%~dp0\WordS-A-Text.dll"
          
cd C:\Windows\Microsoft.NET\Framework\v4.0.30319
regasm  "%~dp0\WordS-A-Text.dll"

)ELSE (

cd C:\Windows\Microsoft.NET\Framework\v4.0.30319
regasm -u "%~dp0\WordS-A-Text.dll"
          
cd C:\Windows\Microsoft.NET\Framework\v4.0.30319
regasm  "%~dp0\WordS-A-Text.dll"

)
