Hi Huy and Kori,
I checked the file SAPAPPL2.log. It seems that during installation your server went down (between 14:43:18 and 15:58:28):
...
(DB) INFO: OIG_TVFTK~0 created #20140404144318
(DB) INFO: OIH03 created #20140404144318
(IMP) INFO: import of OIH03 completed (0 rows) #20140404144318
C:\usr\sap\PIE\SYS\exe\uc\NTAMD64\R3load.exe: START OF LOG: 20140404155828
...
And later R3load complain about task files:
(TSK) ERROR: file C:\Program Files\sapinst_instdir\BS2005\ERP60SR3\AS-ABAP\ORA\CENTRAL\SAPAPPL2.TSK.bck already seems to exist
a previous run may not have been finished cleanly
file C:\Program Files\sapinst_instdir\BS2005\ERP60SR3\AS-ABAP\ORA\CENTRAL\SAPAPPL2.TSK possibly corrupted
C:\usr\sap\PIE\SYS\exe\uc\NTAMD64\R3load.exe: job finished with 1 error(s)
I recommend to begin from scratch. Delete your installation (either by SAPINST or manually)
a start installation over. Alternatively you can try to rename all .bck files.
Regards,
Andrej
