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.

Error 403 Installing any application

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:
