Hello David,
I am sorry to hear about the difficulties you faced using our Control Panel.
The Progress Control Panel's login flow is based on communication with the localhost, so could you please check whether there is something that might be blocking the communication between it and our application? Could you also please verify that the following services have access:
- www.telerik.com
- identity.telerik.com
- dl.telerik.com
- dle.telerik.com
- telerik.s3.amazonaws.com
- downloads.cdn.telerik.com
If you are currently logged in to our website I suggest going to Your Account page logging out and then launching the Control Panel and try logging in from there. If this doesn't help, it would be very helpful if you could send us a log of the web requests when the installer tries to connect.
Telerik FiddlerCap is very useful for that purpose. Here is how to generate the log:
1. Download and install Telerik FiddlerCap.
2. Launch Telerik FiddlerCap.
3. Make sure Decrypt HTTPS traffic is selected.
4. Click on Start Capture.
5. Launch the Control Panel.
6. Reproduce the problem logging in.
7. Click on Stop Capture.
8. Save the session and send us the log (the SAZ file).
Could you please try to perform my suggestions and let us know in case the issue still persists?
I am looking forward tо your feedback.
Regards,
Yana

Hi there,
I am having this issue suddenly, and I don't know how to fix it.
I attached the saz file (renamed to avoid extension validation), so that you can help me to solve this problem.
Thank you.
Hi Dan,
As mentioned in the previous post could you please check whether communication with the localhost is allowed? This is essential part of the log in flow and it cannot complete without it.
Another suggestion that could help in resolving the issue by your side is cleaning the local authorization cache. When Remember me is selected, the Control Panel will try to use the local authorization cache. If that cash is available and inconsistent, the login flow will not complete successfully causing the same problem. Please, follow the steps below to remove the cash:
1. Launch Registry Editor and remove the following keys.
- HKEY_CURRENT_USER\Software\Telerik\AccessToken
- HKEY_CURRENT_USER\Software\Telerik\RefreshToken
- HKEY_CURRENT_USER\Software\Telerik\UserId
- HKEY_CURRENT_USER\Software\Telerik\Email
2. Launch your default web browser and remove the cookies cache.
3. Launch Progress Control Panel.
4. Uncheck Remember me.
5. Try to login into our Control Panel
Meantime you can consider the offline installation packages (MSI) as an alternative to Progress Control Panel. They have wizards which will guide you through installations, upgrades, modifications, etc. You can find them (as well as all of your product artifacts) on your downloads page.

Hi,
I'm having the same symptoms, only I'm trying to install a trial so I can 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 opened Regedit, and under HKCU\Software there is no Telerik folder.
Fiddler saw an HTTPS CONNECT to dle.telerik.com:443, which responded with HTTP202 (Accepted) to this POST:
POST https://dle.telerik.com/metrics/v1/events/errors HTTP/1.1 Accept: application/json Authorization: Bearer {snip} Accept-Encoding: gzip,deflate Content-Type: application/json Host: dle.telerik.com Content-Length: 1211 {"Type":"HandledError","SessionId":"f2ee3acd-37dc-487a-b5ea-1b2647a2eeb3","Source":"Installer","SourceVersion":"2023.3.1012.0","Timestamp":"2023-10-23T21:10:19.7047547Z","OS":"Windows 10 Enterprise 64-bit v.10.0 ","CLR":"4.8","MachineId":"6uI7wmYbX4Q9h0+vgpSj5xbBF4o=","Exception":{"OS":"Windows 10 Enterprise 64-bit v.10.0 ","CLR":"4.8","MachineId":"6uI7wmYbX4Q9h0+vgpSj5xbBF4o=","Message":"The system cannot find the file specified","Type":"Win32Exception"},"ErrorDetails":" at System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo startInfo)\r\n at System.Diagnostics.Process.Start()\r\n at System.Diagnostics.Process.Start(ProcessStartInfo startInfo)\r\n at Telerik.Sso.SsoClient.MakeAuthorizationRequestInBrowser(Int32 port, String appProtocol, String appName, String productCode)\r\n at Telerik.Sso.SsoClient.GetAccessToken(String appProtocol, String appName, String productCode)\r\n at Telerik.CommonInstaller.DataAccess.RuntimeServiceClient.GetAccessToken(String appProtocol, String appName, String productCode)\r\n at Telerik.CommonInstaller.Application.Services.AuthenticationService.Login(String user, String password, Boolean rememberCredentials, Boolean useRemembered)"} HTTP/1.1 202 Cache-Control: private Content-Type: application/json X-Frame-Options: DENY Strict-Transport-Security: max-age=31536000; includeSubDomains X-Content-Type-Options: nosniff X-XSS-Protection: 1; mode=block Date: Mon, 23 Oct 2023 21:11:55 GMT Content-Length: 0
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.
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.
Also, "answer" was the only option to comment on this thread. Perhaps your forum UI could have a "comment" option also?
Hello David,
We provided an answer to the initial in the other thread you opened.
As for the comment option, it is present as seen in the image I attached (bottom left). Maybe the button is not as visible as the one for answering the questions and that is something we could improve.
Thank you for your feedback and do not hesitate to get back to us in case you have any other questions.
