Unsuccessful installation of "Prerequisites and Common Tools

I have installed apr64081113211en, and reboot the machine,  but when I try to install  apm64081113211en , there will be always show message: " Unsuccessful installation of "Prerequisites and Common Tools for AutoPLANT Applications" version - 8.11.13.211 is found. Please install it properly " .   But I have installed the prerequisties  apr64081113211ent without  error message  beside Bentley Connection client, because I have installed it in other application of Bentley.

BTW, I found there are message in regedit database:

HKEY_LOCAL_MACHINE\SOFTWARE\Bentley\Plant V8i\Prerequisite\InstalledStatus   : -2760

Do you know what's wrong on it?  Thanks a lot
