The installation process will inexplicably stop in the third step, making it impossible to select the product to be installed.

The installation process has been stuck on this page and will not continue. Then, nothing has happened.

What version of the program are you trying to install?

[勇张_13119710 · Accepted solution]

The Version is prime 10.0.1.0. 

However, I've just installed it this morning， and the process was exactly the same as last time, but this time there were no more errors and it was completed smoothly.
