SAP/Sybase doesn’t 
officially support running SCC on Windows 8. This seems to be more of an issue with the InstallShield installer. Seriously, why do people still use InstallShield??
If you try installing SCC 3.2x on Windows 8, you’ll get a nasty error when you run setup.exe or setupconsole.exe:
You *can* install and run SCC 3.2.x on Windows 8 if you are willing to run the 32bit version of SCC. You will need to install Microsoft C++ 2005 SP1 x86.
Next, open a cmd.exe as Administrator and run “setup.exe -i gui”
