No, it froze again at the same spot. It appears to be sitting in the cabinet.dll when it freezes, in various functions that look like they're compression related. The nLite binary seems to be obfuscated too, so looks like a lot of work to find out what is going on. Is there a way to get a trace/log that might shed more light on this? I don't think it is just me being impatient... 40 minutes of compression seems excessive.
