hi all

today i tried to install 5 different ut3 demos taken from 5 different mirrors and all of them have an error

During the installation of the physx driver (i haven't one), a data1.cab file is missing or corrupt, or a crc error in winrar (have the newest version)

windows xp home sp2 (formated 2 days ago)
amd x2 4200+
2 gb ddr
nvidia 8600gt (163.71 driver)
90gb free space

someone has a solution for this problem?
