Community Edition - tinnyXML.cpp Error

  
Hi,

I´m trying to install a new instance of "Outsystems Community Edition" but Im getting this error:

Assertion failed!
Program: C:\Outsystems-AgilePlatform-setup.exe
File: tinyxml.cpp
Line: 173

Any ideas?
I have checked all requirements for installation (w2k3, SQL Express, Framework2.0, IIS Correctly configured, etc...).

Best Regards,
Rafael Pereira
