So what your saying is you have an extractor program like "WinRar" or some other one correct?
If so, extract the file to a place you can find, desktop, "my documents" where ever. After it has extracted go to start, programs/AcesHighII/AcesHighII film viewer. Once the viewer opens, in the top corner click file,open. When that window opens click the "browse" button and browse to where ever you save the extracted file. Double click it and it should start.
