Recent Slicer Preview releases (that use ITK5) fail to start on computers with Intel Core i7-3770 CPU. Slicer does not start but instead this error is shown in a popup:

The application was unable to start correctly (0xc0000142). Click OK to close the application.

Windows application log tells that it is an exception 0xc000001d (Illegal instruction) in ITKIOGDCM-5.1.dll. Attaching a debugger and looking at the disassembly I found that indeed there was an shlx instruction where the exception was thrown, which is a BMI2 instruction that is not supported in 3rd-generation (3xxx, Ivy Bridge) CPUs but only in 4th generation (4xxx, Haswell) and later.

We should either change build options to disable using BMI2 instruction set or check CPU type in the launcher and show a warning if non-compatible CPU is found.
