Draftsight x64 will not run from first installation

Hi I have downloaded and installed Draftsight on a Win7 64Bit platform. When i launch the application it loads but has a pop up in front prompting for save of a crash dump.

If it choose do not save it closes the program

If I choose save it saves a chrash dump and then closes.

The error message at the bottom of the Draftsight screen is unsigned add-in Exporttable.dll

I have reinstalled and also tried renaming the users/appdata/roaming/draftsight folder.

I have attached the crash dump

Thank you in advance

Al
