I posted this as an answer on the thread https://www.telerik.com/forums/cannot-log-into-progress-control, but because it's preventing my team from deciding whether to go with Telerik or one of its competitors, I thought I'd repost it as a question.

When attempting to install a trial version of the Blazor UI controls, I am unable to progress beyond the Login step. This is unfortunate as without the trial I can't make the case that my company should spend thousands of dollars on Telerik instead of, say, Syncfusion. I have to say this experience is not encouraging.

I examined the conversation between the installer and the mothership using Fiddler. The endpoint dle.telerik.com:443 responded with HTTP202 (Accepted) to this POST:

So, something is throwing an exception and keeping me from evaluating whether to give Telerik money.

One thing which may be important: the installer requested local disk access that required me to run it as a local Admin account. That account is not the domain account I used to register for Telerik. Not that it should matter; since the admin account has never seen the Telerik account, I would expect that the installer would ask for credentials instead of trying to use non-existent cached credentials.

It occurs to me that a better response to a login failure with cached credentials might be to ask for new credentials. Otherwise the end user might get frustrated and file a very snarky bug report.

Please advise. I'm expecting to give my informal evaluation to my team tomorrow at 3pm CDT/20:00 UTC. I'd hate to exclude Telerik from consideration merely because we couldn't load the free trial.

I am using telerik version 2014.3.1024.45 with Asp.Net Webforms and Recently i have upgraded to jQuery Version from 2.0.3 to 3.6.3.

i am using Telerik Grid control in my application. Every row in a grid has a checkbox. if clicked on checkbox or on a row, that particular row will get selected. This functionality is used to work with jQuery 2.0.3. but after upgrading jQuery Version to 3.6.3, row is getting selected only when clicked on row, row is not getting selected when clicked on checkbox.

As the title suggest, when I install Terlik controls by running the control panel as a local administrator account, the tools don't properly setup in Visual Studio 2017 for my standard account.

Due to company policy, installations on our desktop have to be completed with an administrator account different than our regular user account.    So, the only way for me to install the tools is via a different account.   This installation "works", and all Telerik is installed on my desktop, but Visual Studio does not recognize Telerik when I run my standard account which is used for development (see "StandardView.jpg" attached).

If I run Visual studio under the administrator account, the Telerik menus, toolbars, etc.. show up in Visual Studio (see "RunAsAdmin.jpg" attached), but then I am unable to develop due to our security policy restrictions.  I have to develop in an account different than this administrator account, but cannot with the Telerik tools.

Is there a method to make this automatically install for my standard account as well when installing with the admin account?

 

Thanks,

Russell

I'm having a very weird error when trying to install any application using the Progress Control Panel, it doesn't matter if it's a trial or a free app or one of my licensed products.

My network connectivy it's just fine, I can log in to the app sucessfully and even I can access my account from the web and download the .msi for any application/package.

Log of the error:

Like most things with Telerik these days, the progress control panel is quite confusing? Is it dead and not supposed to be used? If not, why isn't it on the download page? And if it is dead, are we actually supposed to add necessary NPM source manually?

 

What is the recommended way to install and maintain Telerik products and configuration?

Is there a problem with the current version of the control panel installer? When I run it, it extracts to a folder under the users Temp folder (AppData\Local\Temp). It previously used to install itself into the program files (x86)\Progress folder. Any current installation does not get updated and every time you try run it, you get the message that the control panel is outdated and needs to be updated. Except that the file for the new version does not do that

 

Version is: 2021.2.1110.4
