How to run two versions of Java (older and newest)

MY computer has the following:


OS Name Microsoft Windows 7 Professional
Version 6.1.7601 Service Pack 1 Build 7601
System Manufacturer HP-Pavilion
System Model AV131AV-ABA e9105z
System Type X86-based PC
Processor AMD Phenom™ II X4 820 Processor, 2800 Mhz, 4 Core(s), 4 Logical Processor(s)
BIOS Version/Date American Megatrends Inc. 5.22, 4/15/2010
SMBIOS Version 2.5


What I am trying to do:


Run two different versions of java.  Ver. 1.60_20 on Chrome Ver. 31 and Ver. 1.7.0_60 on IE 11 or get the java console to actually work the way it supposed to by enabling one version or the other and only that version run, ultimately I would like for the java console to work properly.


What I have done so far:


I have two version of Java installed.  Ver. 1.6.0_20 (620) & Ver. 1.7.0_60 (760).  I need to have 620 to be able to access a building automation system called TAC.  I uninstalled all java and then installed 620 and bingo I can log in and the java works, but only using Chrome (ver. 31).  It did not work with IE 11, which I can live with.  I then installed 760 in a separate folder from 620.  I went to java control panel and enable only 620 but not 760. see attached scrnshot, but this did not work.  It appears it still runs 760 even though only 620 was enabled.  Below is what happened after installing 760 but having only 620 enabled.


Once logged in to the TAC system and java starts up I receive this security warning see attached scrnshot1


After checking the “I accept the risk and want to run this application” box and then clicking on “run” I get the error message in red

see attached scrnshot2


After clicking on “Error:  Click for details” it gives me this application error message.

See attached scrnshot3


After clicking on “Details” it gives me this message from the Java console.

  See attached scrnshot4.



In conclusion:


I have scoured the internet looking for away for this to work, but have not found a good solution.


Any help would be greatly appreciated.

Hi scomar :)


I don't know if that will help you, but I found an article by Oracle on their websites that fully explains you how to manage multiple versions of Java on one system if you would like to check it out :
