Dear Hope u r fine. i m new to this thread and a few days ago i found a link on this thread which lead me to download HTRI v6 and successfully i dowloaded and ran its exe file on my pc but the only problem i m facing is that after installing the software and making its short cut on desktop when i try to run it asks to put black or red hardware key (USB). Can you plz help me in this regards to get rid of this error so that i could be able to design HE's on this software easily????
