Now I'm using NIS2008 (Kabbah installed by home and company), which was activated by the original NIS2007 installation. I also have the previous NIS2007 China retail picture file, which has two versions. The mdf image file of NIS2007 Chinese original (10.2.0.30) is 353M, and the capacity of loading it into virtual cd is 308M. The iso image file of the Chinese version of NIS2007 (10.4.0. 13) is 24 1M (100.3M when packed into a zip compressed file), and the capacity loaded into virtual cd is 24 1M (similar to. These two versions are the image files above 200 m and above 300 m that you discussed upstairs. Whether it is genuine or not depends on the digital signature of the installation program and whether it can be activated by phone. Different versions of the installer have different digital signatures. You must reinstall to upgrade to the new version. Online update cannot update the version. As for activation, you can activate+crack by phone, which seems not to rebound much. In fact, it is very convenient to use the virtual CD-ROM. You can right-click to load/unload the image of the virtual CD-ROM without opening the main program of alcohol. However, if alcohol is not installed, the right-click menu will not come out, and it is easy to rebound into an unregistered version. []
