Trying to run .net from AutoCad


A friend has programmed an add-on for AutoCad that I had hoped to use in Intellicad. The problem is right from the start when I run NETLOAD I get this message:

Could not load file or assembly 'accoremgd, Version=, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
Cannot load assembly: C:\Users\ahoskin\OneDrive - SRK Consulting\Documents\Resources\AutoCAD\Scripts\Scott Ramp Tool\ACAD Mine Design Tools\Vantage.AMDT.dll

Is this just a limitation of Intellicad that it can't use AutoCad libraries? Has anyone experienced this and found a solution or work-around?
