Problem installing 2.0.3

Hello there! I am having some troubles when installing Dynamo 2.0.3, I uninstalled previous versions and then downloaded this version from dynamobim.org, it installs but just before finishing the instalation progress, this window pops… twice, I “accept” it and it comes again, “accept” again and then it’s gone! the folder ‘Program Files --> dynamo --> Dynamo Core --> 2’ is created fine, but only contains the readme.txt file…

Any Ideas?? thank you!
