Can you please let us know the grasshopper and Rhino version  please.

This may be the cause :

1)      The image at the path in the pic was never created (may need to run as admin?).

2)      The user doesn’t have access to the image (security permissions - may once again need to run as admin?).

3)      The image name changed, or it was moved.

From memory, if they restart Genoform, it should connect to GH and re-make those images, shouldn’t it?

If this is the case, then hopefully they can restart Genoform and it will work.

If they haven’t right clicked Genoform and run it as admin yet, do that.

Depending on their computer settings, the images may not have been created initially because genoform was disallowed the rights to do this. Right clicking and running as admin will fix this.

Pls let me know if this issue is resolved ?
