After upgrade to windows 10, ACAD unable to see mapped drives

[Anonymous]

Company decided to upgrade our PCs to Windows 10. I downloaded yesterday afternoon and ran the setup as I was leaving work. Came in today and finished the install. Everything seemed to be fine.

I started up ACAD (LT 2017) and I usually click on a dwg from windows explorer to open the file. It tries to open up another ACAD and then tells me the file does not exist. I have tried to go tto the drop down menu in ACAD, File, open, etc. When I do this, it does not see any of the mapped drives. My drive on the company server is not found.

Funny thing is, I can click "desktop" and open one of the folders I have saved there. I have shortcuts to certain areas on said drive. I can access the DWG that way.

Has anyone had a problem with ACAD not recognizing mapped drives after upgrading to windows 10?

Hi josh.gilliard

Welcome to the Autodesk Community!

To get files to open properly, I suggest rt-clicking a file in Windows Explorer, use Open With and then select the AutoCAD Drawing Launcher as the default Application.

As far as the drive mapping is concerned, I have not seen this in AutoCAD LT 2017.

One solution for this problem with earlier versions was this:

1. Right-click the desktop shortcut.
2. Go to Properties > Compatibility Tab.
3. And under Privilege Level uncheck “Run this program as an administrator.”
4. Click Apply and OK.

You could check this and see if it makes any difference.

To verify, you can see these mapped drives in Windows Explorer yes?  Can you open Options in AutoCAD LT to see if any of your support paths that use these drives maps are present also? I see, with a little web surfing, that this issue is fairly common on Windows 10 with elevated applications. Some answers indicate to turn off UAC (I do this by default).

Other answers indicate that Net Use doesn't always work and that the drives need to be mapped in Group Policy.

I suspect the issue is a Windows 10 one and not an AutoCAD one but It would be great to find a solution.

Please look at the above and post your results.

DWG launcher was the default program. Also, in the windows 10 settings where you can select your default apps, DWG files were set to open with DWG launcher. I changed that back to ACAD app and I have also unchecked the "run program as administrator" from the compatibility tab.

It seems to working fine now. It sees the mapped drives from the "File/open" drop down menu within ACAD .

I am marking this as solved.

Thanks again

Similar problem, but can't see the network drive in our office when looking for xrefs.

The main drawing opens fine, but overnight, all xref paths have broken because we now cant see the server from autocad directly. All shortcuts work to the server (through autocad), but the path is different.

Basically, I have lost sight of the mapped drives within ACAD.

Help!

I was having the same error. I have a mapped drive to a localhost folder. This is a strange windows issue[1]. It happens when opening a program as Administrator. Problem persists as a different error ("Error opening file") when the file is opened through recent items.

So don't run in administator mode? I right-click and "Run as Administrator" is set to bold, meaning it will default running in administrator mode. I am not sure how to change this. I am on Windows 10 machine.

Since you are posting a me-too reply, how did you "upgrade to Win10" exactly?
And did you try the suggestions posted yet? Which ones, and what happened?

I upgraded to Windows 10 a while ago through System admin. This problem popped up yesterday morning. And it was working fine before.

I did not create a new user account to try to isolate the problem (I don’t have those rights). But I tried creating a new CAD profile, and tried resetting AutoCAD, but the problem continued.

I am able to work around the issue by opening the file through a different shortcut icon, from the start menu instead of the desktop. And it worked. Right clicking on the “faulty” icon has “Run as Administrator” in bold. But it has “open” also, and that also makes it work.  Checking properties on the icon, under compatibility tab, "run as admin" is not prechecked.
