When I start User Subscription License, nothing happens, and login dialog box is not displayed

This problem indicates that a specific dependency is missing, or that antivirus is blocking our software.

Please go to Control Panel -> Programs and in the top right search field enter:

C++

Please check the results, since you should have these:

Microsoft Visual C++ 2015-2022 Redistributable (x86)

Microsoft Visual C++ 2015-2022 Redistributable (x64)

For example:

If one or the other is missing, please note that you can find X86 and X64 installers on the following page:

https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#visual-studio-2015-2017-2019-and-2022

Download the one you are missing and install it, and then start your User Subscription License and check if that has fixed the problem.

If problem is still present, and login dialog box is not displayed, please check your antivirus to make sure that it is not blocking our product.
