the solution is this:
FIRST uninstall tia portal, TIA unfortunately suffers much the hierarchy of the upgrades installed, that should be done in order.
THEN:
1- install Step7 Basic V11.0 SP2 (about 3 gb and more)

2- install WinCC Basic V11.0 SP2 (about 3 gb)

3- install WinCC Basic V11.0 SP2 Update 1 (about 6,5 Mb)

4- install Tia Portal V11.0 SP2 Update 2 (about 1,2 Gb)

5- open the Tia Portal and install HSP 0015, 0022, 0024, 0026

6- once install the HSPs, finally install Tia Portal v11 sp2 UPDATE 3

In my computer it works this way, because I initially tried to put 0026 with upgrade 3, but it gave me the same error. So I tried it and it all works.
