yup x64 OS requires java 32 and 64 bit installed.

I think he's asking about using both 6 and 7.  I think it used to be necessary to have both the old and new versions of Java installed at the same time, at one point you could have had three versions installed.  Today, I don't think it's as important, though I still do it.  Other opinions?

 

Cheers and Regards

About java version 32 and 64 bit:

 

SUMMARY

64-bit Windows operating systems (which may be Windows 7, Vista or XP) come with a 32-bit Internet Explorer (IE) browser as the standard (default) for viewing web pages. These operating systems also include a 64-bit Internet Explorer browser, however using it is optional and it must be explicitly selected to view web pages. Note that because some web content may not work properly in a 64-bit browser, we recommend using the default 32-bit browser and downloading 32-bit Java.

he was referring to JRE7u21

@myselfidem

exactly as I stated both are required for complete compatibility across 32/64 bit processing on a 64bit OS.

Yes, you're right user_hidden, we can read on the same link above:

 

DOWNLOAD INSTRUCTIONS

Click on the item below that represents your set up:

• 32-bit browser, you need to download 32-bit Java (recommended)
• 64-bit browser, you need to download 64-bit Java
• Both 32-bit and 64-bit browsers, you need to download both 32-bit and 64-bit Java, respectively

 

 

Thanks and regards

2 hints about the Problems with the Control-Panel Errors on Win7 X32&X64:

 

1.) Install FIRST the x64-Version, and after them the x32-version on 64bit-Systems

 

2.) Add this Registry-Entrys for Win7:

 

for 32-bit/Win7 (eventually Vista, too?):

 

REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /v "%ProgramFiles%\Java\jre7\bin\javaw.exe" /t REG_SZ /d "WINXPSP3" /f >nul

 

 

for 64bit+32bit/Win (evtl. Vista, too?):

 

REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /v "%ProgramFiles%\Java\jre7\bin\javaw.exe" /t REG_SZ /d "WIN7RTM" /f >nul

 

REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /v "%ProgramFiles(x86)%\Java\jre7\bin\javaw.exe" /t REG_SZ /d "WINXPSP3" /f >nul

 

 

 

This normaly solves the Problems with not starting, or sporadic not starting, the Java-Controlpanel.

 

The Program-Compatibility-Service must be enabled, too.

I figured out, that the x64-Version was only working with "Win7RTM"-Mode, and the x32-Version is running in XPSP3-Mode on Win7,

For Vista i have no clue at the moment, which Settings are needed here...

 

Hope this helps some peoples to finaly fixx this boring errors ;-)
