Problem installing SAP B1 v9.0 on windows


I'm having the very same issue as this question:

However I tried PALANIAPPAN ARUNACHALAM's answer, but nothing, tried reinstalling from scratch, still got "Authentication against the specified License Server has failed. Check your SiteUser password"

TCP/IP already enabled on SQL Server, Server tools installed, I can access to License Manager Server, already running, SQL Browser in automatic mode, and nothing, there's no possible way I can install it, still got same message.

Already tried changing localhost to, always on port 30000, nothing happens, tried on win8 x64, and win server 2008 R2 x64, with SQL Server Enterprise 2012 x64.

Does anybody knows how to effectively fix this?

I just want to try SAP B1 with SAPB1Admin password, I can't figure out how to solve this, already tried everything on that post.

Thanks in advance!

PS = If you need further explanation let me know!

In file "C:\Program Files (x86)\SAP\SAP Business One ServerTools\System Landscape Directory\apache-tomcat-6.0.35\logs, sld-stdoutXXX.log, there is an error "java.lang.RuntimeException: Could not generate DH keypair".
