New Inventor session opens when I open a new drawing

[ChrisBorthwick]

Every time I open a new drawing a new Inventor session starts up and the drawing is opened in there. It's ok if I go through file-open etc in a current Inventor session but I don't want to open drawings like that all the time. If I open 5 drawings at once they start up in 5 seperate Inventor sessions! I can't seem to find an option to change this, is it an inventor problem or windows?

Thanks!

It does not work like that for me, all documents open in the running session.  So I asked around and the only suggestion I could get is to use the task manager to kill all Inventor and explorer sessions.  Restart explorer, then restart Inventor.  Inventor registers with explorer, and it might prompt a re-registration.

This might not help, but it's all I could come up with.  If I get anything else I'll let you know, though.

Hi ChrisBorthwick,

It might help to tell others the version of Inventor and Windows you're using.

example:

Inventor 2013 - Service Pack 1.1

Windows 7 - Service Pack 1

I hope this helps.
Best of luck to you in all of your Inventor pursuits,
Curtis

The proper methodolgy is to start Inventor first, make sure that you are using the correct Project file, then select New and then the required drawing template.

It sounds like you are doing something else such as using Windows Explorer to navigate to where your drawing template is stored. If this is the case, then a new version of Inventor will open.

Seems to be a new behavior in 2020, and it's really annoying. Would open from the double click in previous versions of Inventor all day in same session. Have been using inventor for 15 + years this is a new annoyance. The issue for me isn't opening a "new" drawing it's opening everything In double click in new sessions. Existing things. things I need to copy and paste leader text from etc. ..

@t_fransman  Not a new intended behavior.. My 2020 opens files from explorer in the same session/instance..

Have you tried this https://knowledge.autodesk.com/support/inventor/learn-explore/caas/sfdcarticles/sfdcarticles/Opening...

Thats for ipt files.. If drawings aren't working correctly just adjust for idw files (or Inventor.DrawingDocument if looking at the registry settings)

[t_fransman]

it is new for us here and pretty much across the board. Never had the issue before. The r click open with thing creates a duplicate entry. We tried that to get it to stop opening in read only mode all the time first. That was also annoying. See jpg attached/ 

[t_fransman]

ddeexec Data [open("%1")] was set for all across the board. I think it has to do with the new read/only mode. Because I had to do a open with to get it not to open everything in read only mode for most users. And now it has multiple instances under open with.

@t_fransman  Have you loaded all updates for Inventor 2020?

You can clear out the OpenWith by going here and removing the duplicates from the registry editor..

\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.idw\OpenWithList

[t_fransman]

yes all users have all current updates. May need more instructions on dup entries for the regedit. if possible.

@t_fransman 

Open rgedit

Go to this location \HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.idw\OpenWithList

Delete all keys where the value data is "Inventor.exe". (heck you can delete any a,b,c,d,e.... keys)

Close regedit

repeat the "Open With" process to set the correct "Inventor.exe" program and select "always open with"

Should look like this when done basically..

We tried this and the "open with" r click menu persists even after a re-boot to have two instances. ugh

@t_fransman  Show me an image of your registry settings just like I posted.

You are making the registry delete/change for "idw" files and looking at the right click menu for an idw file right?

Hi! This behavior may not be dictated by application like Inventor. It is somewhat if not totally, by Windows. This has something to do with "dde" or "ddeexec."

Here is what I found. Launch Regedit.exe and go to the following keys.

Computer\HKEY_CLASSES_ROOT\Inventor.PartDocument\shell\open\command

Default = "C:\PROGRA~1\Autodesk\IN2AA9~1\Bin\Inventor.exe /dde"     (make sure double quotes are removed)

Computer\HKEY_CLASSES_ROOT\Inventor.PartDocument\shell\open\ddeexec

Default = "[open("%1")]"                         (make sure double quotes outside of the brackets are removed)

You will need to also check "Inventor.AssemblyDocument" and "Inventor.DrawingDocument" additionally.

Try it out and see if it works.

Many thanks!

[t_fransman]

Thanks, Johnson Shiue

But those settings are things I've already verified. The problem still persists on several of our work stations. Any other ideas??? Also I made an error I am using 2021 windows 10 and all available update are installed. My mistake. 

[johnsonshiue]

Hi! I am sorry I am running out of ideas also. Try something and see if it helps.

1) Right-click on the Inventor 2021 desktop icon -> Properties -> Compatibility -> check "Run as Admin."

2) Start Inventor.

3) Close Inventor and uncheck the option on Step1.

Many thanks!

johnsonshiue

nope didn't work. Ugh

[t_fransman]

Yes i tried that. I then figured out if you go "open with" when it's doing it wrong. Ya just have duplicates of the program in the "open with" you kill those it fixes it unless you use view in window, which i liked the Inventor light view only thing however, this problem makes me not want to use it because as soon as i do it creates a multiple instance in " open with" and always uses the new instance. So I don't view in window anymore, problem solved ( sort of ugh ) >?
