Almost all users who actively use the Internet download various utilities and are passionate about games, downloading updates and additions to them, they encountered the error "the file is not a 7z archive." This problem is solved quite simply. But before you correct the error, you need to know its cause.
Causes of the 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 archived files. It occurs most often in the following cases:
- The archive is faulty or was archived with errors;
- An archived file does not have an extension;
- a problem with the operating system that has ceased to recognize installation files.
Archive defective
Sometimes it happens that an error arises due to a problem in the zarivanny file itself. If the archiving was done with one's own hand, then apparently something went wrong and the process went wrong or failed, as a result of which the inscription “the file is not a 7z archive” began to appear. In this case, you just need to redo the process of archiving the necessary data. By the way, it is advisable to always check the serviceability of the archive.
It also causes the problem "the Opera" (or any other browser) with which the installer was downloaded is not a 7z archive. Perhaps something went wrong during the download process: the download was interrupted due to lack of internet, a sudden browser close, etc. In this case, you need to either download it (go to the downloads in the browser and click "Resume"), or download it again.
Do not also exclude the option of a malfunctioning file that is being downloaded. To do this, you need to download it again and, if the situation has not changed, download a similar one from another source (the benefit of data on the Internet and on torrents is plentiful).
By the way, problems with the installer or archive itself are the most common cause of the problem "the file is not a 7z archive." What may be to blame for the one who posted this file on the site from which it was downloaded. Therefore, it is worth looking for a similar document somewhere else.
Without identification marks
It happens that the installation file with the extension ".exe" and the archives ".rar", ".zip" and others do not have the extension. Because of this, the operating system cannot attribute this object to any program to open it. Perhaps that is 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 immediately, but hope still remains.
For Windows 7, the algorithm is as follows. Right-click on any document and select "Rename." This is done in order to see whether the extension can be changed or not (it will be after the name through a dot, for example, a new document. Doc).
If the name is displayed along with the extension, then we put the desired extension on the necessary file. If not, then you need to configure its display.
Open the launch, go to the "Control Panel". There we go to the section "Design and personalization". In the window that opens, go to "Folder Options". We move to the "View" tab, in which there is an item "Hide extension ..." at the very bottom and from which you need to uncheck. Now you can try to fix the error "the file is not a 7z archive."
If an object without "identifying marks" should be an installer, then put its extension .exe and rename it again. If the archive, then .rar, .zip or .7z, which can be opened by archiver programs WinRar, 7zip, PowerArchiver.
Trouble with the OS
Also, the reason that the object "is not a 7z archive" may be the Windows 7 operating system itself. Rather, it ceases to perceive objects with the .exe extension, which makes it impossible to start them. Therefore, before performing further actions, it is worth trying to run other installation files and make sure that they do not work either. Correct the situation in this case too.
We go to the start and in the search we write the query “Run” (or press the key combination Win + R). In the window that appears, write regedit.
Now we go along the following path: HKEY_CLASSES_ROOT // exefile // shell // open // command. Here we are interested in a register file called "Default".
Now you need to click on it and in the column "Value" write the following: "% 1"% * (starts with a quote and ends with an asterisk, the space is also taken into account). The registry editor closes , we reboot the computer.
