Thanks for help with Trial License. I was able to get a real error this time that I should be able to address with network people. I think they tightened up security and won't let us hit the specific PLC port 49210. That's my current guess.

Softwaretoolbox wrote back that they found the license, and they sent us a copy. You said it was very old. Do you recommend we upgrade? I intend to move this application from an installed .exe physically on local computes to just run as part of our web applications with the output as a webpage instead.

You've been very helpful btw.

rIt is possible, so I have reached out to Software Toolbox. I checked our payables records and found nothing under your name or software toolbox, so this must have been purchased with a credit card. I can't get to credit card records until Monday when payables is back in the office. Thanks again for your help.

In the mean time, is it possible to use a trial license or something like that? I just want to run this locally to get the real error coming out of the PLC, instead of the you dont' have a license error I"m getting now. The "real" problem is almost certainly network/permission/security that we recently added.

Thank you for reply. I do not physically have the license file, but it would have been sold to Sterilite Corporation originally under the name Brian Moore possibly number 1954229880. Can I get a license file?

Hello, your questions helped me partially resolve the problem. I am now back to the original issue, a license error. Please see the screenshot with the new error.



I will answer your questions anyway just in case they are still relevant:

1. If you hover mouse over the green underlined Import-s, does it show any error hint? If so, what is the message?
The imports shows these errors, but this was resolved by actually having the DLL in the path of the reference:


2. Click on one of the OpcLabs assemblies under References (in the Solution Explorer on the right). What does it show then in the Properties window for that assembly? Can you post the picture here?


3. If there is a non-empty Path in the Properties above, does the file referenced by that path actually exist on the disk?
The path did not exist. I created path and dropped some files in I found in one of his other projects. I have no idea why he put the references in the debug bin.

4. Are you doing this on the computer where the project has previously been developed, or are you trying to build on a different computer?
I am trying to do this on a different computer. The previous development computer was wiped.

Thanks so much for answering over the weekend.

Thanks,
John
