CLR20r3 error [SOLVED]

Kalispera,
I have a problem with installation. After launching the setup.exe and after the downloading that the program performed, the process stops and give me this log:
"Description:

I'm not a software expert so I cannot understand. What I did wrong? I'm installing the software on a 2nd Pc, not running fsx, only complementary addons, like ASN FSinn and so on, Win7-64.
I have a registerd copy of FSuipc.
Thank you.

SOLUTION:
Try this : Open Internet Explorer (not any other browser) and download Adobe Flash Player.
When done, reboot and try to install OAV Acars.

Yes!!! Thank you Stavros. Even if it's my fault, as a better reading of the manual highlight the fact.
