Thank you for your reply

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Install JRE 7u25 in STATIC Mode
Install JRE 7u45 in STATIC Mode

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I really want to used two versions of JRE 7 on workstation
  - On version for browsing (Intenet Explorer)
  - On version version for Business Application
ACTUAL -
If you install a version higher than the JRE on workstation, it takes over.
The installation is in STATIC Mode.

• Is it normal when installing two versions in STATIC Mode, the latest version will delete keys, modifies and replaces other files?
• Normally the STATIC mode is for cohabite a multiple versions of JRE7.
• What must we do to avoid this problem when installing a version higher than JRE found on the computer?
