Draftsight program stops working with windows 7 64 bit

I have installed Draft sight 2015 on a dell m2800 with a AMD Fire_pro W4170m driver version 13.352.1002.

It installs without issues but at program startup it encounters a problem that causes it to stop working and windows needs to close it.

I have repaired, uninstalled reinstalled, tried Draft sight 2014, updated video driver to version 14.301.1010 but the problem remains. With the new driver I was able to activate 2014 before it stops working. Restart does nothing.

Anyone have any ideas??
