Files open in read-only mode

[Mark_Geurds]

Since a couple of minutes all my inventor files (ipt, iam, dwg) are opening in read-only environment by default. My settings are:

-File opens in inventor 2020 (rmb> open with, 2020 is selected)

-The 'normal' properties doesn't have the box 'read-only' ticked.

I can't find anything in the iProperties, regarding this subject.

Is there someone who can help me?

Are you open Inventor or are you opening Inventor Read Only mode?

Make sure what one you're opening ... this was a new feature added for 2020

I have Inventor Professional 2020 opened, yet when I double-click any Inventor file it opens the file in Read Only (new instance). When i drag the file in the professional it opens there. I've just checked my regedit-> root and there it says open in RO. I don't know what I've done to set RO as default but it is in every file-type. Very annoying and I don't prefer chaning things in the registry. Do you know what caused it?

Make sure you're using the right Icon they are pretty much the exact same.  

I have the full version icon in my start.   

Might try doing a clean uninstall / reinstall .. 

last thought, make sure you're file association / open with is set to the full EXE and not the read only option.

What you are mentioning is what I've experienced with 2019. This got me thinking, the 2019 version was never uninstalled, so I did that and now every Inventor file is opening in 2020 professional. I don't know how, I don't know why, but it's working again? Even in the regedit the string is changed to inventor instead of invRO. I'm baffled, but it's working so yeah, lets see where we will get! Thank you for your response.

Update:

When first time opening Inventor Professional every Inventor file opens in the same instance.

When opening a file in RO (Read Only), every file opening after that is opening in RO in a new instance. When selecting 'open with' it shows two same Inventor icons, yet I now know the second one is the Professional, but if i click on it it opens a new instance of Inventor professional. Very annoying and I'm trying to contact our PC-guy to fix this. Any help will be very helpful! (yes I've tried to change strings for opening in same instance in registry but it doesn't seem to work).
