How would I reinstall our copy of AutoCAD 2016 onto a new system? The user that originally purchesed the application (as a company employee) has left the company and I'm not being asked to install it on his replacement. We have the installation files, but I keep running into an issue where I get an error saying that the connection is lost (see attached screenshot).
How can I get this installed?

Welcome to the Autodesk User's Community..
You actually don't have the installation files.. You have a link to the web-installer and thus you get the message you're seeing.
Download and install per:
1. Clean out your personal temp (%temp%) folder. Set Windows UAC to never notify, full admin rights, and if possible disable your Anti-Virus/Malware scanning utilities. Also the download should occur over a hard wired connection to the Internet and not over WIFI.
2. Access the Autodesk Virtual Agent and follow the download links to your product.
3. Download all of the parts (some applications only have a single part to download) for your product first. Do not continue until all of the parts have fully downloaded.
4. Navigate to your download folder location and extract (double click) part _001_00X.sfx.exe (or the single file download).
5. In a few seconds the extraction will start and prompt you to extract to C:\Autodesk.
6. Once the extraction is finished, the installation will automatically start.
7. Follow the installation steps for your product. At this point you could cancel the installation or create a deployment.
However if the installation does fail using this method, please post your installation log file here so we can review it. Posting info: Sometimes installation log files contain personal information such as your serial #. Prior to posting your log file please make sure to remove such info.
Good luck on your installation and report back on your progress.

Autodesk Virtual Agent is just a place to download the common Autodesk applications. There's no account needed. But you will need your serial # that was assigned to your company for the installation. Do you have that info? Do you have a reseller? If you do they can provide all that information to you. We are only users here and don't have access to any accounts.

No problem.. Chat with an agent here and see if they can assist you by given your company name and as much information as well. However they may also not hand over that information due to security reasons but its worth a try. @natasha.l anything else to add?

Light bulb went off.. 
Do you still have AutoCAD 2016 running on another machine? IF you do, launch the application, select help (upper right hand corner of screen) - Circle with a question mark
Select About AutoCAD, when the dialog appears select Product Information. In that dialog should be your serial #.

@Mark.Lancaster yeah it happens. 
Hello @Anonymous,
You can also locate this information in C:\Users\user name\AppData\Local\Autodesk\(product info.html) activation information is saved here it includes the request code, product key and serial #.
Let us know if you have figured this out. Thanks for posting.
