I've installed last OpenVPN Connect for Windows v.3.1.0.361 x64 on Windows 10 (1903) and then I uninstalled it via "Add and Remove Programs".
I couldn't install it after that. Installation just didn't complete and made rollback.
I found a workaround. I installed OpenVPN Connect for Windows v.3.1.0.361 for 32bit OS and after that I could install OpenVPN Connect for Windows v.3.1.0.361 x64 just over it (while and when 32-bit version was installed).
In my tests and several reinstalls that way I made a mistake: I correctly (Add and Remove Programs) uninstalled 32-bit version. I couldn't and can't install both versions after that (32-bit and x64).
Could anyone help me to find a solution?
OS reinstallation isn't an option. I think there is some flag which doesn't allow me to reinstall software. I tried to find it by ProcessMonitor, but, all I found as yet, that the installation broke on one of the wmic requests.

I run installer with log and it returned this error:
CustomAction InstallDriver_CA returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)
By the log: InstallDriver_CA = C:\ProgramData\OpenVPN Connect\drivers\tap\amd64\
It seems that installer can't add tap driver second time.

Found an error in MSI. tapinstall.exe, included in MSI just can't install TAP driver.
tapinstall.exe in tap-windows-9.24.2-I601-Win10.exe works fine.

Installation process now on Windows 10 seems that way:
1. Install OpenVPN Connect for Windows v.3.1.0.361 x64
2. Install tap-windows-9.24.2-I601-Win10.exe
3. Replace C:\ProgramData\OpenVPN Connect\drivers\tap\amd64\win10\tapinstall.exe by the C:\Program Files\TAP-Windows\bin\tapinstall.exe file.
4. If you want, you can uninstall tap-windows-9.24.2-I601-Win10.exe after that.
5. In cmd.exe with Administrator rights:
"C:\ProgramData\OpenVPN Connect\drivers\tap\amd64\win10\tapinstall.exe" install "C:\ProgramData\OpenVPN Connect\drivers\tap\amd64\win10\OemVista.inf" tap_ovpnconnect
OpenVPN Connect for Windows v.3.1.0.361 works and connects fine after that on 10-th Windows and you don't need to turn off UAC or SmartScreen.
P.S.
Thank you for "help". 🙁
