    I'm having a ton of problems getting RadAjax controls to work.  I've spent the better part of the past 24 hours trying to resolve this with no luck.

    I started to receive the error on a website (not a web application).  Single project, no solution file.

    Could not load type 'Telerik.Web.UI.RadUploadHttpModule'.

    I thought that odd that it started since the previous run didn't have any errors and I don't use the upload module in this website.

    I've tried everything to resolve this.

    First I deleted anything to do with Telerik and reinstalled.  This did not solve the problem.

    Second, I removed all references to Telerik from web.config then manually added them all back in from another website.  This did not solve the problem.

    Next, I deleted all the lines referencing the upload module and uploadprogress from web.config.  After doing this I received the following error:

    Could not load type 'Telerik.Web.UI.RadCompression'

    Next, I deleted all the lines referencing RadCompression from web.config.  After doing this I received the following error:

    ASP.NET Ajax client-side framework failed to load.

    I have also done the following:

    Uninstalled and reinstalled the 4.0 Framework.

    Tried the 4.5 Framework

    Tried the 4.5.1 Framework

    Uninstalled and reinstalled VS 2012

    Uninstalled and reinstalled VS 2013

    I thought since this was an Ajax issue, I should try other browsers.  I was using IE 10.  I tried Firefox and Chrome and no problems.  Or so I thought.  Since I had removed the references to upload and compression, ajax worked fine.  But once I put back all the Telerik references the errors continued occurred in Firefox.

    I then tried a test scenario. 

    I created an empty website.

    I added one page, default.aspx.

    I added Ajax to the site.

    I ran the site.  It ran fine.  Blank page rendered (which was expected since there weren't any controls on the page)

    I added Telerik to the site.

    The same issues occured, first the upload module issue.  I removed the references in web.config.  Then the radcompression issue.  I removed the references in web.config.  Then I received the ajax error.

    I uninstalled IE 10.  The errors continued to occur with IE 9 (Windows 7, 64 bit, reverted to IE 9 on uninstall of IE 10).  I installed IE 11.  The errors continued to occur.

    We use Telerik 2011.3.1115.40 at work.  A buddy of mine has 2013 Q1 & Q3.  We tried with both of those.  The error occurs in all three versions.

    I have tried other websites we have in development and the errors occur in all three.  Only I have the problem.  Nothing has changed on the computer.  Windows Update is not set to automatic.

    I am at a complete loss at this point on what to try next.  I am completely at a standstill with my development.

    Below is the full error for the upload module.  I can send the test site if needed.  Let me know how.

    Server Error in '/' Application.

    Dan,
    I'm getting the "Could not load type 'RadCompression' " problem.
    It worked fine. I checked a small change into TFS. I reconciled my workspace after the build was complete.
    I resumed some work. I tried to run it and got the above error.
    I've tried everything I can think of (I'm working on a rather large web app solution.)
    I don't have the luxury of removing Telerik and starting over.
    Any idea how to get this to work!? I've wasted over a day on this and am at a standstill, too!

    Thanks,
    Bruce
