Attack a gamer called "File is not a 7z archive"

Almost all users who actively use the Internet, download various utilities and are passionate about games, downloading updates and additions to them, met with the error "the file is not a 7z archive". This problem is solved quite simply. But before correcting an error, you need to know its cause.

Causes of error "file is not a 7z archive"

This problem often occurs during the launch of standard installation files with the extension ".exe" (they are often called "setup"), and, of course, in the archived files. It occurs most often in the following cases:

• The archive is defective or has been archived with errors;
• The archived file does not have an extension;
• Problem with the operating system, which has ceased to recognize the installation files.

Archive failed

Sometimes it happens that the error occurs because of a problem in the zarivirovannom file. If the archiving was done by hand, then apparently something went wrong and the process failed or passed with an error, as a result of which the inscription "the file is not a 7z archive" began to appear. In this case, you just need to re-run the process of archiving the necessary data. By the way, it is always advisable to check the integrity of the archive.

It also causes the "not 7z archive" "Opera" (or any other browser) problem that was used to download the installer. Something went wrong during the download process: the download was interrupted due to lack of Internet, sudden browser shutdown, etc. In this case, you either need to download it (go to the downloads in the browser and click "Resume"), or download the new one.

Do not also exclude the option of malfunctioning the file that is being downloaded. To do this, you need to download it again and, if the situation has not changed, download a similar from another source (the blessing of data on the Internet and on torrents is enough).

By the way, problems with the installer or the archive itself are the most common cause of the problem "the file is not a 7z archive". At what can be the one who laid this file on the site from which it was downloaded. Therefore, it is worth looking for such a document somewhere else.

Unmarked

It happens that the installation file with the extension ".exe" and the archives ".rar", ".zip" and others does not have an extension. Because of this, the operating system can not assign this object to any program to open it. Perhaps, that's why the computer writes that the installer is not a 7z archive. What to do in this case? The answer is simple: you need to put the necessary extension. Of course, there is no guarantee that the document will work right away, but there is still hope.

For Windows 7, the action algorithm is as follows. Click the right button on any document and choose "Rename". This is done to see if you can change the extension or not (it will be after the name through the point, for example, a new document.doc).

If the name is displayed along with the extension, then we put the desired extension on the required file. If not, then you need to configure its display.

We open the start, go to the "Control Panel". There we go to the section "Design and personalization". In the window that opens, we go to "Folder Options". We move to the "View" tab, which contains the item "Hide extension ..." at the very bottom and from which it is necessary to remove the mark. Now you can try to fix the error "the file is not a 7z archive".

In case the object without "identifying signs" should be an installer, then we put its extension .exe and rename it by new one. If the archive is .rar, .zip or .7z, which can be opened by WinRar archivers, 7zip, PowerArchiver.

The trouble with OS

Also the reason that the object "is not a 7z archive" can be the operating system itself of Windows 7. Or rather, it ceases to perceive objects with the extension .exe, because of which it is impossible to start them. Therefore, before you perform any further operations, you should try to run other installation files and make sure that they also do not work. To correct a situation and in this case it is possible.

We go into the start and in the search write a request "Execute" (or press the combination of keys Win + R). In the window that appears, write regedit.

Now we pass along the following path: HKEY_CLASSES_ROOT // exefile // shell // open // command. Here we are interested in a register file called "Default".

Now we need to click on it and in the "Value" column write the following: "% 1"% * (starts with the quote and ends with an asterisk, the space is also taken into account). The registry editor is closed , we are rebooting the computer.
