I have an installation problem with Hw 12.0 on windows XP. I followed the download instruction from the Altair's email and download the file'hw12.0.1_win64.exe' (~42Mb). When installing the hyperwork suite, the executive files are empty.I tried a few times. Do you have any idea or instruction for download and installation? HyperMesh is the target software I need to use. Thank you.
