I did not receive a serial number in my e_mail to test the product.

Dear Claudio,

We did send the key to try Thinfinity VirtualUI.
Any chance you got the email captured by your anti-spam filter?
Please check your mail again.

You can always write to or open a chat session to request the trial to be sent to you again.

I do not get the serialnumber

Dear David,

Otherwise, please open a chat session to request the trial.

David, have you received it ? Is it serious this offer?

Hi Daniel! We offer a free trial key to anyone who wants to test our software.
If you wish to try Thinfinity VirtualUI or any other application, contact us.

I installed on current Windows 10 with VC2019 as directed, non-load balanced server and dev environment. I did get the trial serial number successfully activated. Starting the app gives your “Welcome” splash, but start web browser just brings up a Firefox 73.0 window of “Application Load Failed – license not found”, and after a delay the Winform starts as usual on the desktop. Please advise?
