I've participated in the Windows Insider program for a while. Experience Windows Feature Experience Pack 120.2212.3530.0 Windows 10 Home, 64-bit operating system, 圆4-based processor I also used it for quite some time on a 32-bit Windows 10 Home box, where I upgraded to v1.4.0 around August, 2020, without any problems. On this PC I tried several older versions (not all), but the only one that did not fail was Outline-Client windows-v1.2.0.ītw, I'm not new to Outline as I'm using it to connect to the same server from my Linux Dual Boot on this same PC with the latest Linux version of Outline-Client installed. I expected the installation process will run from beginning to the end without an error message and after install, the Outline-Client will let me connect to ther server. Under the hood, this will get the device name "Ethernet 2". In case of a trial to run the installer again, as suggested by the message, a new tap device labeled "TAP-Windows Adapter V9 #2" will be added to the list of Network adapters in the Device Manager. This is what is shown in the device manager before installation.Īnd here is what's shown after the failed installation:

Whenever I uninstall the application, remove any tap device from the device manager and reboot the PC before I try to reinstall, I get this same error code #3. Sometimes I've got another Error code (I've seen 1, 2 and 3, but never 4). The problem can be reproduced each time I try to install the application. During the installation of Outline-Client 1.5.0 I get an error code 3.ĭespite of this message the application has been installed and can be started, but if I try to connect to the server the connection fails.
