embedded browser x64 Wildfire 4

Has anyone implemented the Microsoft hotfix for jscript described in CS46526 for x64?

Does this apply to 32-bit only?

We are running W4 and x64 embedded browser, with both x64 and 32-bit Java installed.

Thinking we need to launch regedit from SysWOW64 and value would be set with QWORD(64-bit) instead of DWORD (32-bit) value?

Thanks!
