Specified path fail when installing desktop version

I have problems when I try to install the desktop version. I had the the same problems in diferents desktops running win XP or win 8. Always appears the message "ERROR ON APPLYING TRANSFORMATIONS. VERIFY IF THE SPECIFIED TRANSFORMATIONS PATH ARE VALID". What should I do for solve this problem?

Obs.: Original message in portuguese - ERRO AO APLICAR TRANSFORMAÇÕES. VERIFIQUE SE OS CAMINHOS DE TRANSFORMAÇÃO ESPECIFICADOS SÃO VALIDOS.
