Installing windows 7 update

I got that same error when I installed the W7 RTM, but I ignored it and the installation succeeded anyway. I used the tool attached below, but when I tried to locate it online, the following webpage said that it had been discontinued due to some GPL issue:

Means the version of UDF used on the disk cannot be read by the current OS or DVD Drive, i.e., does not support it.

I'm not sure why everyone is skipping this, but this is your explanation. It sounds like the disc burned properly. I had trouble reading the original Vista .isos from TechNet on some XP computers.

If you need to access the files within the .iso for some reaosn, you can extract them with several utilities, such as the suggested 7-zip. If you are trying to install the OS, boot from that disc.

Well, I am trying to analize this problem

It isn't a problem though. It's normal behavior. Logicearth had the solution. If you want to see it yourself, take a Vista disc and try to read it in some various XP or older systems.
