I see that that Universal Extractor includes i*comp, which includes ZD50149.DLL, ZD51145.DLL and ZD55131.DLL---three libraries which are, from my understanding, the property of Acresso Software Corp. Were these libraries licensed for unlimited distribution, or does no one simply care anymore? Or is the code in limbo since InstallShield changed hands? I can't find any conclusive license terms for them.
