The database in ### could not be opened

[bradeneuropeArthur]

Hi,

We have the following problems with an inventor dwg.

We open any inventor test.dwg created new with inventor.

If we do SaveAs test2.dwg in Inventor we receive this message!

The database in C:\Vault\Projects\12\test2.dwg could not be opened

This only on one specific workstation

We use inventor-suite 2018 also Inventor-pro 2018

Hi! I am not aware of a reproducible corruption leading to the exact error. Please make sure all critical Windows updates are installed and the graphics driver is updated. Install the applicable Inventor updates to your Inventor release. Clean up %temp%.

Did you recall what you did before the file became corrupted?

Many thanks!

Hi Johnson,

Thanks for prompt response.

My colleague was working on the file from home and his VPN connection went down. It was restored but when he went to save the file (I think) he got the error. I just tried opening it myself and same error. Will have to confirm update status as the PC updates are dealt with by our support team but I had emptied %temp% the day before and I have the latest update offered - 2024.1.1

From previous posts it sounds like it's a known issue - is it addressed specifically in any updates?

Hi Nick,

I don't believe we are aware of a workflow leading to such corruption persistently. If you know how to reproduce it, please let us know asap.

Many thanks!

Used this work around and didn't loose any work - great.

I then finished this drawing, saved it and because it was similar to my next drawing saved it as the next file and replace model references.

Worked on that for half a day including saves and went to save at end of day to be greeted by "The database etc"

So, same again - copied sheets into a new file to carry on and saved over corrupt file. Wonder what tomorrow will hold?

Had the same problem with an Inventor dwg. Couldn't open it, because of the mentioned problem. Opened the problematic drawing in AutoCAD Mechanical and I was prompted with a message that the drawing had issues and was asked if I wanted to have the error(s) repaired. Confirmed this and the drawing was repaired. Saved and closed the drawing, reopened it in Inventor and the problem was gone. No loss of work. I guess this only works when you use Inventor drawings in the dwg-format instead of idw-format.

Hello, I have the same problem as of recently. I tried this suggestion but it didn't work for me. My Region & Locale were already set correctly. I'm running INV 2024 Pro on Win 10. Any other ideas?

Also I think it's a corrupted file because only one has been affected. I would hope to get this file back as there isn't an Old Version copy from the same timeframe, I lost about a day's worth of work, lol.

thanks

Hi! Unfortunately, this is an unrecoverable corruption. Except finding the backup files from \OldVersions\, there isn't much you could do to recover the file. I suggest you looking to using a PDM system (Vault or UpChain or Fusion Team).

Many thanks!

[ross_sapienza]

oh well, as I suspected. I wish we had Vault up and running already, or at least some sort of automated backup.

thanks for the reply

[nicksEK29Z]

Hey Bluegoose2, did you try the other workarounds mentioned in the thread? I had no luck with the region settings but could recover file by copying sheets to new drawing and others have managed to open in ACAD to repair?

[ross_sapienza]

it's happening again... why is this a problem? all I want is to run inventor .DWG drawing files. I come back after the weekend and the DWG file is now corrupt, it was fine on friday when I left. this is super annoying after I had just explained to my boss that I prefer INV.DWG over INV.IDW for compatibility issues. Fortunately the correct oldVersion file still exists (this time), but I can only open it as "old version (save not allowed)". 

"The database in C:\Users\...\Drawer.dwg could not be opened"

Hi Ross,

Something is wrong. I suggest you use AutoCAD RECOVER command to open the Inventor dwg template file and the other affected dwg files.

At any given time, has more than one user open the same dwg file and edit at the same time? If yes, this is a bad workflow. Another place to check is Windows Control Panel -> Clock and Region -> Region -> Administrative -> Change System Locale -> uncheck "Beta: Use Windows Unicode-8 for worldwide language support."

This option is known to corrupt Inventor and AutoCAD dwg files.

Many thanks!

Hi John, Thanks for the follow up.

1.) it's pretty rare any of us would run the same Inventor file(s) simultaneously as most of our smaller projects are not shared work and we are a small office, and not all of us bother with INV.DWG drawing files. 2.) I checked the "Clock and Region" settings and everything was normal, as well as the "Beta: Use Windows Unicode-8 for worldwide language support" was already unchecked, I don't think this option was ever on. However I didn't notice the comment before about opening the INV.DWG file with autocad (not running mechanical currently), I tried this and nothing happened and the "corrupted" INV.DWG file showed no signs of error within autocad 2022. Should it be 2024? The first time this happened, the current oldversion file wasn't there and the DWG wouldn't open in autocad either (I think). However, what did work was opening the latest oldversion INV.DWG (this time) and was able to save as an IDW, it worked without having to copy sheets to a new file.

thanks again

Greeted with this error several times over the last few days:

As some others have mentioned, the the "Beta: Use Windows Unicode-8 for worldwide language support" was already unchecked.

In this case I'm having repeated issues with the same file.  I've been forced to pull an old version from Vault to get it to open.  After editing, I save it & check it back into the Vault without issue.  When I go to open the dwg again (from Vault or from my local machine), I get the database error.  Obviously frustrating.

It's kind of funny how this thread, or issue has been marked "solved" .. because it is not. Apparently this is on-going and is a unknown glitch with inventor DWG drawing files. It's not the end of the world but is causing productivity slowdowns obviously and should be addressed, if possible. thanks 🙂

Interestingly, it appears that I was able fix my Inventor dwg by using AutoCAD.  Here are the steps I followed:

1 - Open AutoCAD.

2 - Select open & browse to the location of the Inventor dwg on local drive.  Open the file in AutoCAD.

3 - Error message displays.  Select "Recover."

4. Review recovery message .  Select "Close."

5. Save file & close AutoCAD.

6. Open Inventor dwg from local drive using Inventor.

7. Review error message & select "OK"

After following those steps the Inventor dwg appears to be functioning normally again.

[ross_sapienza]

Yes, that is very interesting, AutoCAD used to fix inventor.dwg files. Makes sense though and the next time this happens I will try these steps. This was mentioned before, however the last corrupted inventor.dwg file I had didn't invoke the recovery option, even after trying to run the drawing recovery manager utility.

I should say that my previous response to the thread sounded rude and I would like to apologize for that.

thanks everybody

Hi Johnson,

This issue is happening to my company right now. A user worked on a drawing from Vault for several versions and suddenly, yesterday, he couldn't even open from Vault. He mentioned it to me (Autodesk support) and my solution was to GET the assembly locally then open the drawing locally. I get the same problem with "The database cannot open...). Then, if I open the assembly in Inventor, I open the drawing (while assy is open) and get the message that drawing has a reference with that assy that has been resolved to the same file, then I can open without problem. After putting the drawing to Vault, all happens again. I told the user to create a new drawing, he did, and after a few versions in Vault, all happens again.

I created a new drawing based on the same assy file, after a few versions in Vault working fine, it happens exactly the same. (The database cannot open...)

I've tried a few other drawings from Vault that are based on other assemblies, get the same issue.

I don't have selected that Clock and Region setting.

I tried Autocad to Recover, but it butchers the drawing, make it all lines. At one point, after recovering with Autocad, i couldn't even open in Inventor.

So it looks like I can replicate the issue.

What suggestions do you have?

Thank you
