Error (-5006:0x8000ffff)
The error -5006 : 0x8000FFFF is an InstallShield error which does not seem to have a solution, yet: http://community.flexerasoftware.com/showthread.php?s=&threadid=122633
You may have the same problem with any other InstallShield setup.
However you can try to resolve this issue by renaming the InstallShield folders in %appdata% and c:\program file\common. Furthermore you may have to rename all InstallSield registry keys.
