TestExecute Crashes on Windows32 bit System

Hi Support, 

  I have a 32Bit Windows32bit system. 

I have downloaded the free trial Installers for TestComplete<TestComplete_T30355177848.exe> and TestExcute.

I notice that my system crashes when the TestExecute  binary is started( have a 400MB Dump File).

The same Executable runs on a 64bit Windows7 System. Kindly let me know the Supported Version and any recommendations for Installation.

regards,

Vikram
