Security permission issue when run Excel from ACAD

[harryliu3140]

Greeting to all experts in this group.

I'm new to .NET and try to write a VB.net program to read information from EXCEL sheets to ACAD.

I got this security permission issue when the program try to setup a Excel application.

Anyone know how can I get around it?

Thanks.

Is your dll on your hard drive or network

Thank you Jeffery for your quick response.

Really my dll is on network. The problem solved after I move my project to C drive.

I'm so glad to solve the problem with one post after several days waiting for email from my colleague.

This is a great group.

Have a nice day.

If you need to place the dll on a network, do a search on CASPOL.exe, it is the command that sets the security on machine to handle access to network based .NET dll files.
