I can't install PT 10.3.6

I currently use PT 10.3.2 and it works perfectly on my setup.
I can't install the 10.3.6 version, the installer hangs on the execution of the scripts of the package.
Who has already experienced this problem to the installation?

Thanks in advance for your help.

(No problem with installer from PT 10 to PT 10.3.2, via 10.2 and 10.3)
