lots of customers experience 'invalid Unity file'

Hi,

On several sites, we've put Unity content, but users seem to get the 'invalid Unity file' error. This is odd. Most of the times on the Windows platform, sometimes with FireFox 3, sometimes IE6 or IE7.

E.g it appears here:
http://www.rijveiligmetmedicijnen.nl/view/page/simulator

I would really appriciate if people responded with "OKAY" or "PROBLEM" after checking it out, so that we can see what's wrong with the template (we use the default template).

Thanks

 

Mac OS X 10.5.2
Firefox 3.0.3
WORKS
(although the stuff near the middle of the viewport is wobbly, as if it was being reftacted, made me nauseous )

 

Thanks for checkin'!

It's a gimmicky racer ("medicin simulator"). You've been injected with a medicin that'll blur your vision and changes respondse time.

We're busy with a few new projects and experiencing the same "invalid Unity file" issues, so that's why were curious.

 

I get 'Invalid Unity web file'. The loading progress bar doesn't get all of the way across before it fails.

 

Invalid Unity web file

Mac OS X 10.5.5, Firefox 2.0.0.17

BUT: Works fine in Safari

 

No problems here in Safari or Firefox, OS X 10.4.11.

Hi,

It's "Invalid data file".
We are using Linux to host the content (our own dedicated web server).
Wouldn't this result in the same errors with browsers and OSes?
Is it a MIME setting?

The double extension is a mystery. When I build the project it is appended automaticly.

Works fine here on OS X 10.4.5 Safari

 

To add: Re-installing on Windows IE7:

Code (csharp):

1. error opening file for writing: C:\program files\unity\webplayer\mono\2.x.x\mono-1-vc.dl

 

WORKS. Safari. OSX 10.5.5

 

Hi,

I have renamed it. Now I am trying to add the mime on the server.
What is the exact MIME type for Unity?
(Is this application/unity3d ?)

It would be nice if people who had problems, tried again now that I have added the MIME type. Thanks! This could be a solution for in the Wiki.

Thanks!

 

ps:

If it is a MIME problem, how can it be that e.g col000r had issues in Firefox, but not Safari?

 

Noted! Great!

ps: I did add a MIME though. (Application/unity3d)

 

As I recall from a year ago, that double extension occurs when you're upgrading a Unity 1.x project to 2.x. - apparently the .unity3d is appended to the entire filename you used in 1.x. (It was a minor inconvenience and didn't seem worth reporting as a bug, at the time, but maybe it was!)

 

Hi Technicat,

Good to know.
Strange enough it's v2.0 only

 

I don't have a solution, but I have had scattered reports that this was happening as well. So presumably it's happening more but most aren't bothering to try and contact someone about it. There hasn't been a good opportunity to get further information.

Hmm that is worrying. Do you have info on which browsers this happens or does it seem random?

I still get reports; it seems this isn't fixed yet :-(

 

10.5.5 / Safari

Works perfect.

 

I filed a bug report on the double extension creation. I reproduced it by loading a really old Unity project which I'd used to create web players before, waited for it to finish upgrade, selected Build Settings from the menu, saw the default target was still Web Player, clicked the Build button, and the resulting Save As popup has the entire original player name as the default, including the .unityweb extension. If you hit Save then you'll get a file ending .unityweb.unity3d. If you remove the .unityweb from the filename before hitting Save, you're fine from then on.

 

OSX 10.5.5
Firefox3

works perfectly

 

OsX 10.5.5
Firefox 3.03

Shows the loadbar but the it says Invalid Unity Web file

 

Error

OSX 10.4.11
Firefox 3

I notice that everytime i reload the webpage, the progress bar went a little further. So i reloaded like 6 times and the game worked, but the first 5 times i got the error Invalid Unity File.

.org

 

Darn.

I still get lots of error reports, daily!

The double file extension is clearly not the issue here, so I have to investigate.
It's important that our client believes in Unity, because they are now under
the impression that it is "inmature technology".

I get the same reports from other servers, and I'm totally out of ideas here.
Is the streaming stuff buggy, does Unity 'think' it's been downloaded, but in fact, it's not?

Jeroen

 

We might have something similar.

 

Hi,

Check your webserver config (e.g Apache). There are several variables that determin the time-out of accepting requests. Shorter numbers are better for e.g small files which are often requested, like banners. Larger numbers are better when it comes to bigger downloads (but the load on the server gets 'heavier').

What might be happening is that those variables are set too low. This results in the webserver "giving up too soon". The result is that the Unity plugin (?) thinks the file has been downloaded completely, but it hasn't, so an error occurs -> it cannot start.

It helped our situation!
Secondly, check your MIME settings and add Unity as filetype.

 

If anyone needs help about setting MIME TYPE - you can try the following if you are using IIS6:

Open IIS > Web Site > Properties > HTTP Headers Tab > (Mime Maps) File Types ... > New Type:

Associated extension: .unity3d
Content type (MIME): application/vnd.unity

 

works

Mac, Firefox

 

OSX Leopard on Intel based mini mac, running safari. no problems.
neat game. keep it up.

 

I've seen this in the other day also frequently when visiting various sites with unity webplayer content. Seems fine now though.

 

I met this problem too, but it was really MIME's problem.
I added the item of application/unity3d in the MIME list of server2008 IIS.
Than, problem solved.

 

I'm having the same 'invalid unity web file' error. It's working when on the hard drive, but not on the server (apache).

I've tried adding the mime type, but it didn't change anything.

Is this the right way to do it? :

' AddType application/vnd.unity .unity3d '

Yes I can confirm I had the same problem and was getting crazy because it worked when i used it locally on the net but not once i placed it on the webserver.

in this case you need to add a new MIME unity3d as extension and Applicantion as content type.

Now all work ok. :wink:

 

Works.
Google Chrome beta (3.x) Vista 64 bit.

 

Just created a very simple, very small 166kb, unity project. Ran a web build, and uploaded files to my server. Added the MIME type, had the tech at the hosting site verify the MIME type was good, and I'm still getting "Invalid Unity Web File"..

The host isn't blocking the filesize, I've given full permissions to the folder and files, and the MIME is valid..

Any help would be awesome.

 

yes, i have the same problem and my hosting can solve it changing the MIME settings in the server.
BYe.

 

I´m on Windows 7 with Chrome works fine, with Opera works fine, with ie too....

i´m having the same trouble with my project, but i guess is related to that i was uploaded my file to mediafire.com

 

I got the same problem.
It worked locally on my Apache 2.x under IE7 and FF3. But when I tested it on a remote IIS6 webserver under FF3 the progressbar never progressed. In IE7 I got an "invalid Unity file" error.

I found out I got an 404 error (file not found), when I tried to download the .unity3d through a direct URL.

The fix is to add a MimeType Application/Unity3D for files with an .unit3d extension:
Open IIS > Web Site > Properties > HTTP Headers Tab > (Mime Maps) File Types ... > New Type

Worked for me!

 

i got this problem in IE8 so I tried in Firefox, which brought up the initial screen but it didnt load the game.

I went into the MIME settings on my web server and added the extension unity3d with type Application and it now works in both IE8 and Firefox.

 

This thread seemed questionable as a solution, so I am here to re-enforce that this is a VALID SOLUTION.

I just registered here. The WebPlayer worked great when it on my localserver. When I threw it on my site it gave me this error. I updated the MIME for .Unity3d and all i well.


FYI. I downladed this like an hour ago and got a web player for a web browser made quick. I This is a great product.

 

Hi all,
I've experienced this issue before. The solution was including the proper MIME type on the webserver (IIS in my case).
If you are using IIS, and you have ASP.NET installed you can add a new MIME type by including the following in the web.config file:

<configuration>
<system.webServer>
<staticContent>
<remove fileExtension=".unity3d" />
<mimeMap fileExtension=".unity3d" mimeType="application/vnd.unity" />
</staticContent>
</system.webServer>
</configuration>
