This message appears if you don't have flash installed. Chunked Upload (or plupload) will work with many different technologies by default it's Flash but you can change this in a settings file \umbraco\plugins\koiak.plupload\scripts\koiak.plupload.js

Flash is installed on my machine and I don't have any problems using the Multiple Upload Control which also uses Flash.

Is there anything else you could suggest?

Can you see the examples on http://www.plupload.com/example_queuewidget.php?

If yes, then try going into the JS file I mention and setting the options to only be flash. Maybe it's trying to load a different Runtime that you don't have installed.

I can see the examples on the plupload website but still no luck inside Umbraco.  I tried just flash as suggested but this did not work under any browser and I also tried gears too and run Umbraco under Chrome which still showed the error message.

Do you run firebug in Firefox? If so, can you see if there are any other javascript errors. Maybe an error is cause JS to halt and not to get to this point.

I've just tried installing this on 4.0.3 on Win2003 and its working for me. I'm running out of ideas to suggest!

I now got it working!!  It seems that my Umbraco installation was taking exception to the period in the plugin path "koiak.plupload".  I modified the source and recompiled it with the period removed (and renamed the folder) and hey presto, it works!

Thanks for your help, the firebug suggestion helped.

Glad you found a solution (really, I had nothing else!)

would anyone like to update and share the code for 4.5?, i cannot recompile the source to try out removing the period as have an older version of visual studio. Could someone post a link to the files or update the code to work with 4.5 i would me most grateful. Or, direct me to another solution to packet uploading for umbraco, cheers!!

Hi Howard,

The issue isn't Umbraco 4.5 as this package should work fine with 4.5. The issue is an IIS plugin that wont serve folders with periods in it (it returns a 404).

I've updated the package so it doesn't use periods in folder names.

Remember to vote for the package if you like it.

Cheers,

Chris

Hi Chris, thanks for the quick response i will surely vote for it if i get it up and running. Unfortunately, i have tried installing and uninstalling twice but still get the same error, i have tried recreating the data type manually but to no avail. I know this can get frustrating but i apreciate your efforts! thanks Howard

This may be a caching issue. Can you use Fiddler or LiveHTTPHeaders (https://addons.mozilla.org/en-US/firefox/addon/3829/) to check the chunks are being uploaded to the koiak_plupload and not koiak.pluploadfolder?

Just tried myself on 4.5.2 and same thing, No Valid Runtime message is shown. None of the above tricks work :-(

I've never tried this on 4.5, but it should be version independent.

• Can you see the examples at http://www.plupload.com/example_queuewidget.php?
• Can you see if there are any other javascript errors?
• Has it installed a folder called umbraco/plugins/koiak.plupload or koiak_plupload?

Cheers,

I've just tried this on a 4.5.2 installation and have experienced the same error. If you watch the 'net' tab in firebug you'll see there is a 404 on a webresource.axd call.

The JS was never intended to be loaded in such a way, I'll have a look into this later, but let me know if you fix it in the meantime.

Cheers,

Chris

It installed into the underscore folder, cant really see any errors but the link you sent works fine

I tried this yesterday and ran into the same issue ("No valid runtime", 404 in webresource.axd).  I didn't have much time to troubleshoot but it appeared the javascripts weren't loading or getting called at all.  I fixed by replacing the umbraco.library:RegisterJavaScriptFile and RegisterStyleSheetFile calls with Page.ClientScript.RegisterClientScriptInclude and RegisterClientScriptBlock as shown below.

Again didn't really spend time troubleshooting this was just a quick fix:

            // Load in external JavaScript and CSS files
            /*(
            umbraco.library.RegisterJavaScriptFile("plupload1", "/umbraco/plugins/koiak_plupload/scripts/gears_init.js");
            umbraco.library.RegisterJavaScriptFile("plupload2", "http://bp.yahooapis.com/2.4.21/browserplus-min.js");
            umbraco.library.RegisterJavaScriptFile("plupload3", "/umbraco/plugins/koiak_plupload/scripts/plupload.full.min.js");
            umbraco.library.RegisterJavaScriptFile("plupload4", "/umbraco/plugins/koiak_plupload/scripts/jquery.plupload.queue.min.js");
            umbraco.library.RegisterJavaScriptFile("plupload5", "/umbraco/plugins/koiak_plupload/scripts/koiak.plupload.js");
            umbraco.library.RegisterStyleSheetFile("pluploadCss", "/umbraco/plugins/koiak_plupload/css/plupload.css");
            */
            
            Page.ClientScript.RegisterClientScriptInclude("plupload1", "/umbraco/plugins/koiak_plupload/scripts/gears_init.js");
            Page.ClientScript.RegisterClientScriptInclude("plupload2", "http://bp.yahooapis.com/2.4.21/browserplus-min.js");
            Page.ClientScript.RegisterClientScriptInclude("plupload3", "/umbraco/plugins/koiak_plupload/scripts/plupload.full.min.js");
            Page.ClientScript.RegisterClientScriptInclude("plupload4", "/umbraco/plugins/koiak_plupload/scripts/jquery.plupload.queue.min.js");
            Page.ClientScript.RegisterClientScriptInclude("plupload5", "/umbraco/plugins/koiak_plupload/scripts/koiak.plupload.js");
            Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "pluploadCss", "<link href='/umbraco/plugins/koiak_plupload/css/plupload.css' rel='stylesheet' type='text/css' />");    

I've released Version 1.1 that is now compatible with 4.5 (and incorrporates Tom's changes).

I think the issue is related to ClientDependancy framework that was released in 4.5.

Enjoy!
