--- Comment #3 from Berillions berillions@gmail.com 2012-06-13 14:20:59 CDT --- I found a solution for the problems in the 64Bits prefix. I just copied the 2 files PnkBstrA.exe/PnkBstrB.exe to windows/system32.
On Windows, when PB is installed in 64Bits version, these 2 files are installed in syswow64 folder but the services are launched by "system32/PnkBstrA.exe" (i see that when i check in windows process list). It's strange because these files don't exist really in system32 folder...
