Inventor 2014 DWG will not Check In to Vault

Inventor 2014 DWG will not Check In to Vault

I am having issues getting my .dwg files to check back in to Vault Basic. I can get all different types of files (.iam .ipt .idw) to check in without issues, but .dwg files hang and Inventor will eventually lock up.


I've tried disabling Visualization and I still cannot make it past this point. I can even tell it to check in everything at once, and it will breeze through the other files but any .dwgs will hang. Any help would be greatly appreciated.


My PC Config:

Windows 7 Professional 64-bit

Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz


Dual AMD Radeon HD 6450


I'm running Product Design Suite 2014

The file is on the vault server not your local computer. Have you searched there?

Here are the steps.


1.       On all Vault servers, examine the content of the ‘C:\Windows\Temp’ directory for ‘$’. Check your explorer settings if you're not seeing it - this may be a hidden file

2.       Check the file date.  If it is much older than the installation date (or if you want to test this), proceed…

3.       Invoke IISRESET /STOP in command prompt window

4.       Move ‘$’ out of the ‘C:\Windows\Temp’ directory.

5.       Invoke IISRESET /START.

6.       Test DWG check in. - The check in will generate a current version of ‘$’ (you may want to verify the new date).


Hope this helps,

I have the same Problem. Only Inventor DWG will not Check in.

I can´t find the File$ on my Server.

Any Progress on this?

I'm seeing the same thing on a 2012 Server, There is no$ file.

(I turned on hidden files and folder to see if was a hidden file but No luck).

Yes I checked on the actual Server (its a virtual server), and yes I was in the Windows temp folder. (in fact I searched EVERY temp folder, on the server) 

Its base Vault, so there is no file / folder Persmissions (or lifecycles, or revs).

If the file exists its not on this server. ( There was a second server that was taken down on Friday)


Does anyone have a work around for this?

So far we can't check in any dwgs.



Let me know,

Hi all,


Same problem here on just one PC. When checking in an assembly the check in screen freezes (not responding). So the problem is not only on DWG's but on IAM's too. Only in 1 out of 20 check ins the screen not responding appears.


I tried to search for the unddacad file on our server but couldn't find it.


Hope someone knows the solution because it's very frustrating.

Anyone else also having problems completing a copy design that involves an Inventor DWG?

We're getting an error along the lines of "the underlying connection was closed...", and wondering if it's a related problem

All files appear to copy except the Inventor DWG.


Another two weeks with a useless Vault... anything yet Autodesk?

Ok, one of my colleagues did a lot of work on this one.


The, solution, although no one will like it, proved simple.


The problem was ‘Windows 2012 Server R2’ (and, I guess, for others Windows 8.1). It transpires that ‘Windows 2012 R2’ is not a supported operating system for 2014 Vault. The ’UNDDACAD.AC$’ solution just doesn’t work, because in the 2012 R2 operating system, this file, for whatever reason, just doesn’t appear to exist.


Backing up the vault, rebuilding the server with Windows 2012 (not R2), then restoring the vault has solved the problem.


I would welcome a suggested fix, because it is difficult to source and license older operating systems for new servers.

We were having the same issue with the Windows 2008 Server R2 for the DWG drawing files due to the JPG file of our company logo in the Title Block. We were able to remedy the issue by


  1. Open Drawing template which may be found in your directory as highlighted in the attached file
  2. Copy your logo image file to this directory as well
  3. Right clicking on the Title Block and click edit
  4. Click Edit Definition
  5. Right click on the logo and click change source
  6. Change the source file to the one in the directory that you copied

The issue with us was that the logo was not in the correct project folder as the drawing template.


Hope this helps you you.

If you have any questions let me know.

I have had the same problem .

Examineining the content of the ‘C:\Windows\Temp’ directory I didn't find the  ‘$’, so I clen the folder C:\Windows\Temp deleting all ac$ file and the problem was resolved.

The ADMS was in a windows server SO.


Do you Know why cleaning this folder  I can check in the dwg file?


Thank you in advamced.

Best regards.

I am having this same issue with Vault Basic on my machine only.  See attachment for all of the error screen shots.



I too looked into the .ac$ files in the temp folder and I had none.  I was so hoping this was my issue.

I am having the drawing issue not being able to check into the vault along with the random copy design and opening files up out of the vault.

I just wish I could find a solution to this.  Limping right now using Vault.

Just for your information - your solution works also for Vault Basic 2016. Our customer was just after Vault migration to 2016 and he could't check-in any drawing (AutoCAD .dwg., Inventor .dwg nor .idw).

They deleted temporary file (it was 2 years old) according your suggestions and everything has been solved.

Thank you!
