A-If you have already installed Mosquitto on another windows machine e.g. XP and want to install it on another machine e.g. Windows 10 then you can just copy the directory containing the mosquitto files to the new machine.

On freshly installed Windows 10, Openvpn installed normally (no errors). I also tried to remove completely OpenVPN, as it is written in the manual, but it did not help. Since my last comment I rolled Windows up to control point at which OpenVPN worked.

If an update installation is in progress, let that installation finish.

Make sure that you use the correct installer version

You have to use the correct installer version for your operating system version. See How can I tell if my computer is running a 32-bit or a 64-bit version of Windows? to determine whether your system is 32-bit or 64-bit.

Then, download the correct Internet Explorer 11 installer for your system version. To do this, go to Download Internet Explorer 11 (Offline installer), and then locate the download file for 32-bit systems or 64-bit systems, as appropriate.

Installing a localized version of Internet Explorer 11

You can install Internet Explorer 11 in your localized environment by using either the English version of the installer or a supported language version of the installer for your localized environment.

If you don't use the English version of the Internet Explorer 11 installer, make sure that the language version of the installer matches the active language of your operating system. If the language versions don't match, Internet Explorer 11 stops the installation. Additionally, you receive the following error message:

Wrong version of Internet Explorer installer.

For example, you experience a language mismatch if you try to install a Spanish version of Internet Explorer 11 on a computer that is running the Catalan-localized version of Windows. Although Spanish is the base language for the Catalan Language Interface Pack (LIP) language, you must use the specific Catalan version of the Internet Explorer 11 installer in this environment.

To install Internet Explorer 11 in your active language, download the correct Internet Explorer 11 installer for your operating system version. To do this, go to Download Internet Explorer 11 (Offline installer), and then locate the download file for 32-bit systems or 64-bit systems, as appropriate.
