Windows DUA Polling Reconfiguration appears on 1 operating systems as a functional file.

How to open DUP file?

The most common problem when using Windows DUA Polling Reconfiguration is that a specific DUP is not associated with the program. This causes the file DUP to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the DUP file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Microsoft Windows

An often overlooked issue is to make sure that Microsoft Windows is installed on the computer. The easiest method is to use the system search engine by entering the program name Microsoft Windows in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support DUP files.

Programs to open DUP file

Remember to download programs supporting DUP files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Microsoft Windows with DUP files

However, it may happen that the application itself does not cause the DUP file to open in the Microsoft Windows application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the DUP file with the Microsoft Windows program.

Step 3. Update Microsoft Windows to the latest version

If, however, after binding Microsoft Windows with Windows DUA Polling Reconfiguration there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Microsoft Corporation page and install.

Step 4. Check for the following problems with the DUP file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The DUP file may be unusually small compared to the original file. This suggests truncating the DUP file contents when downloading or copying. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our DUP file. As a result of the scan, sometimes it is not possible to recover DUP files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the DUP file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged DUP files. The easiest way to restore the file is from a backup or by contacting Microsoft Corporation, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted DUP files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. If possible, you can try to move the DUP file to another location.
This problem only occurs with more complex files. In this case, the DUP file is blocked by the first application to open it. Closing other programs should help. Sometimes you have to wait for the session to the file DUP to close. However, some background programs may block the DUP file while scanning. If the problem persists, restart the machine.
