PTC Installation Assistant crash

Hello everybody,

I am trying to install demo version of Creo on my Windows 8 64bit machine (Creo Parametric 30-Day Trial). When I start PTC Installation Assistant and than login successfully I am getting application crash report.

This is hardware configuration:

Intel i5

16Gb ddr3

Intel HD 4000 GPU

I tried on Windows 7 and Win Xp Pro, same error.

Any clue?

Thanks in advance!
