Yesterday, the final day of October,One of the DT Administrators,named Copytrooper ,at their web pages,said: "We have to delay v4 for around 14 days due to a serious bug.We worked hard to get it done for a October release, unfortunately s*** happens from time to time.From now on all threads concerning the release date of v4 will be deleted, and people who still complain will get an extra time out from the forum for the next 14 days." As U know,the daemon tools is the best Virtual CD/DVD software under windows. Version 4 is designed for WinXp x64 Edition. Now, I use one software named "FantomDVD" under WinXp x64 Edition,but it has a few bugs ,espacially virtualling those encryped discs.
