Installation of DefGuard Client v0.2.1 on Windows 11 Fails

[pauls-hf]

The installation of the DefGuard client software on a Windows 11 machine always fails.

Asset used is defguard-client_0.2.1_x64_en-US.exe. This is a fresh installation.

Other observations:

• Installation progress window disappears abruptly.
• The progress bar reaches different levels with further installation attempts .
• No error messages are displayed.
• All my browser (Chrome) sessions are terminated (appears to be a forced termination)
