Unity doesn't open from Unity hub

I'm on Windows 10 and I when I open a Unity project from Unity hub, it never opens. The unity splash screen will show up, it'll display for like up to 10 minutes, but it'll eventually close, no editor will open. If I try to open the same project again from Unity Hub, it'll say the project is already open.

I'm able to open the project if I double click a scene file in my Finder (skipping Unity Hub).

Anyone else have this problem?

I should note, I had a problem before with opening Unity Hub in the first place before (Similar to this post). Adding ipconfig to my system variables allowed Unity Hub to open.

 

I had this issue before and I found that by manually opening the editor, it asked me to fetch a new license, which I did. I could then open it with Unity Hub. Not sure if the solution is the same though for you.

 

When I open the editor it doesn't ask me to fetch a new license. I have a pro version activated on my working editor (the installed one that opens if I open it directly).

 

I too am having this issue,

Just to hand over the info asked above.

Editor/Unity Version for project: 2018.1.0b13
Assets > Everything else

Opening the project with the version then using hub seems to fix the issue but still should not need to have to do a workaround when using a commercial product.

 

Just going to post it here, as I have no idea where to send it to.
https://pastebin.com/cQ3EZFmY < Editor
https://pastebin.com/MZn9BBgA < Hub

 

1) I can create projects and it'll open them while creating them
2) Re-installed and still nothing still wont open the project

Another issue is the fact every time my computer is started it asks for the license again.
The whole thing kinda feels like it wasn't even tested correctly before being released.

OS: Windows 7

 

1) Home/Work
2) I have a unity_lic.ulf (will restart and check if it is still there or not, and edit this post if it is still there or not)
3) No, and there shouldn't be one

Renamed it, restarted my PC and it did not ask me to re-activate my license.

 

License not being read seems to be fixed, however, still can't open projects through the hub.

 

1) Yes a splash screen shows up, nothing else pops-up like the loading bars or anything else.
2) It asks for it when just opening the editor, has nothing to do with a project. (normally asks though after opening the hub first though)
3) can do later as have other things I gotta do at the moment.
3.1) Will try opening thru the hub, posting the logs, then opening thru the editor, posting the logs, then re-open thru the hub then post the logs again.

Sorry for the 2nd post.

 

Just bumping this so someone from Unity can see the logs.

 

Constantly getting 'Error launching application: The application path 'C:\Program Files\...Unity.exe' cannot be opened.

Tried giving unity hub administrator rights but it doesn't actually finish opening the main unity hub ui when I do that.

Anyone else having this issue?

 

does the hub ask for a license?

 

Also seeing this behaviour, not launching Unity from the Hub, with the additional situation that pretty much every other time I run it the Hub prompts me to reauthorise my Personal license all over again.

 

i have the exact same problem

 

So to be more specific, Ive waited a day and gone through the whole process again. Here's everything in more detail.

Yesterday when I responded in this thread, the Hub had opened with the the 'machine identification is invalid' error message that JackPS9 links a screengrab of above, and was prompted for license type and the three-option income question associated with the Personal license but not my user account details. So Im not being asked to log in, but I do have to go through other steps to 'reauthorise.'

At that point I installed the latest 2017.4, the final 2018.1 and the 2018.2 beta from the Hub, downloaded some asset store updates in 2017.4, and created a couple of empty test projects, one each for 2018.1 and 2018.2, and filled them with packages from the new Package Manager (which needs a checkbox'd 'load selected' option by the way, one by one is annoyingly primitive and slow).

Note that I couldnt launch any of these from the Hub, so had to launch each one directly, and even though I'd just 'reauthorised' the Hub, I had to 'reauthorise' the first one I launched. I also checked my C:\ProgramData\Unity and there was a Unity_lic.ulf file there timestamped to when I 'reauthorised'.

Today, that Unity_lic.ulf file was still there, and with the same timestamp as yesterday, but when I opened up the Hub again, Im back at the starting point; I have to 'reauthorise' the Hub, I still cant launch any version of Unity from the Hub, and when I launch a version of Unity standalone, I was asked to 'reauthorise' that as well, and my Unity_lic.ulf file has been replaced with a new one.

 

I have also had a similar issue, having to re-authorize each version of the editor from outside the Unity Hub before being able to launch them from the Hub, as TaleOf4Gamers said.

 

I solved the problem like this:

My unity.exe was working as admin and this was causing the problem so I unchecked that admin permission and it opened.

I'm completely unable to use unity (including unity free) because of this bug, I need this to be resolved asap...

Is there an official resolution for this bug and why are we forced to use this hub if it does not work, I never had licencing issues in any of the previous years?

Customer Services ticket #662171

I'm stuck in a loop

 

After digging around forever, I found a link to the problem, apparently it's already a known issue because it's in the unity post from 2015 - https://support.unity3d.com/hc/en-u...258.687927572.1557263367-375701058.1557263367

I needed to delete C:\ProgramData\Unity\Unity_lic.ulf

and reinstall hub... you guys should really do this automatically instead of forcing us to deal with this headache. I'm sure one of your team members can do it..

 

Just to follow up, this is the response I finally got back from support (8 days later..), none of this was the cause, I pointed out the cause last week in the post above. It's a good thing I know how to search the internet. It's also really said to receive this level of support for a know issue of over 4 years.

Why is Unity asking me, and other customers to do this?

Please pass on my findings to support, and get it properly documented to prevent other users from experiencing this bug that completely locks users out being able to open unity - most will not likely find the solution as quick as I have, especially considering Unity support does not even know what to do.

 

I'm only providing feedback to help other users in the future, use it how you will; without the solution I found I'd still be unable to use Unity is all I'm saying.

 

What is happening. one of my project is made in Unity 2018.1.0. now i am trying to open it in unity 2019.0.1. But it is not opening. please help me

 

what is the work around instead of using unity hub? personally it's just irritating to me.

 

I was having this problem as well, and I use a VPN regularly. when I turned off the VPN and tried again, Unity launched as normal with no problems. if any of you are using a VPN or a proxy, try disabling that?

 

Can confirm that disabling my VPN fixed the problem for me as well.

 

I can't open Unity. It just opens Unity Hub. I will not let me open a project. Unbelievable.

 

I am not using a VPN. I am not seeing a license screen. Just a list of projects that I can't open.

 

LINUX 18.My Unity Hub Won't open. i have it on my start page, i click it, but still won't open.
Does anyone else has this broblem?

 

having same issue here seems to be a license issues HUb show license but Unity loads and stops

 

I am experiencing the same bug as others in this thread. I have opened a bug report through the Hub: https://fogbugz.unity3d.com/default.asp?1179270_k32tbfk2b14sml9n

It does appear to be correlated to the recent license renewal in my organisation.

Have others opened bug reports as well? Can you link them here? Unfortunately the Issue Tracker that is being used makes it exceedingly difficult to find related issues. One cannot search by Issue ID either, so weighing in directly in the bug report is nearly impossible if the link isn't shared publicly.

Problems, such as the one in this thread, that have only been reported intermittently over the course of 18 months will only get a serious look from the developers if sufficient constructive noise is made by the community. Send bug reports and link them in the forum thread.

 

Guys the solution is very simple on my side, just disable anti-malware or antivirus, that's it !

 

Thanks! , worked for me!

 

Had the same issue after BSOD - only complete unity re-installing with manually removing Unity folders in C:\Users\username\AppData\Roaming helped

 

Thanks Man!!! You saved my day.

 

Thank you, this worked for my versions
Unity 2019.2.8f1
Unity Hub 2.1.2
Windows 10

 

I'm happy it helped someone after I was told by UT staff it was likely not relevant , I do wish UT was more receptive to feedback... Sorry you had to go through this, I know it was frustrating, I lost a day to it and customer service did not want or know how to help; I think it took them a week to respond to me which is unacceptable for a paid service that is used for work!

 

Not sure if anyone else experienced this problem, but I was unable to open fresh projects created in Unity Hub for any version of 2019.x.x due to 'Invalid Project path' errors.

However, I was able to find a work around by creating a new project using the New button drop-down arrow and selecting the version of 2019.x.x I wanted. Not sure why this solved the issue, but as of 5 minutes ago, this works, so hopefully it helps someone else out.

 

Also getting this issue today after upgrading to the latest hub v2.2.1.

Can create new projects but can't open existing.
Can bypass by opening any project scene directly from windows explorer.
