When attempting to install "ACEmanager.exe" on a Windows 7 x64 workstation I am
getting the InstallShield error 1628 - An invalid or unknown table was specified.
Does ACEmanager.exe install on a x64 Windows 7 workstation?
The application was put in the legacy area which means that it's not developed and maintained anymore. This makes the application as having compatibility issues on x64 systems. You could try setting compatibility to Windows XP which is the only solution at the moment.
