When we tried to run the Opencascade, we got the following error message. File tried to open: TTopology.exe Error message

MDI:Load Accel failure

Following windows were opened TTopology.exe WindowsNT Tdraw Command window

OPerating system: Windows 2000

We had downloaded all files then copied dll files to folders in which respective exe files were stored. This we kept on doing till we got rid of messages like "cannot find somefile.dll" After this we encountered this error, which we are unable to resolve.

thanks Kedar , Vinayak
