Draftsight 64bit

I'm having problems working with Draftsight on our new workstations, installed on W7-64bit.

Installation is ok. When starting the program, we get "draftsight has stopped working'.

When I have a look in the event viewer, the error code is 0xc0000005.

I have done installation with administrator account and with user account (which has admin rights). No luck.

Activation succeeded, but cannot open draftsight.

Same problem on 3 workstations.

Anyone an idea how to solve ?

 

Thx. Wim.
