Installing Illustrator 10 does not work with Crossover Pro 4.0.
I have tried installing dcom95 and 98, different settings of wine's Windows Version (win95, 98, 2000, and XP), and using both the builtin and native version of various OLE .dlls. I've also tried copying a real version of stdole32.tlb into ~/.cxoffice/dotwine/fake_windows/Windows/System.
If I use the builtin ole DLLs (ole32, oleaut32, rpcrt4), the Adobe installer crashes with a message: "Cannot install IKernel.exe". If I install dcom95/98 and use the native .dlls, the installer makes it halfway through and dies installing files, giving an error message that includes the line: 'C:\Program Files\Common Files\InstallShield\Engine\6\Intel 32'
If anyone has better luck, please let me know.
