What to do if Windows can not install the required files
According to the latest statistics, the percentageThe computer systems running the Microsoft-Windows software package are about 91%. In light of this, do not be surprised at the abundance of questions from users who are somehow related to the work of this particular OS. One of the most common ones is connected with the peculiarities of the work of the accompanying software.So, sometimes an attempt to install the applicationcauses the "Windows can not install the required files 0x80070017" error. Similar failures can be connected both directly with the operating system Windows, and with third-party applications.
Although many computer owners alreadypractically abandoned the use of CDs, preferring media on the basis of solid-state flash memory, yet the first are still encountered. One of their disadvantages is the impossibility of error-free reading of recorded data in inaccurate storage and scratches on the mirror surface. Thus, if when working with CDs, when you try to install the application, a system window appears telling you that Windows can not install the necessary files, you need to make sure that there is no damage on the media. Sometimes, to restore efficiency, it is enough to wipe the disc, removing dirt, fingerprints, etc.
In order for the drive to properly read data from the disk, it is recommended to record at a low speed, down to the minimum.In addition, the program for writing should beproperly tuned, so the various functions of "overheating" should be disabled. Finally, remember that rewritable CDs (RWs) are inferior in quality to their simpler R-type counterparts (both + and -). The best option for "curing" is using a flash drive. You can also try switching the mode of the hard drive from AHCI to the IDE in the system BIOS.
Both of the above points relate to the firstthe queue of errors that occur when you install the operating system on your computer. Not less often, users receive a message stating that Windows could not install the necessary files when working with applications. In order to understand the cause of what is happening, let's generalize the process of installing programs. When you click on an executable file, the background data in the intermediate folder is extracted from the background, from which, as from the bricks, a complete set of program files is created in the target directory. If the computer has anti-virus protection and has detected a danger in one of the unpacked files, access to it is blocked. And since often the user is not even informed about this, the result is a system error "Windows could not install the necessary files". Thus, when this happens, you can try to disable anti-virus protection during the installation of the application.If the re-installation passes without errors, thenthe reason in the antivirus or, indeed, the presence of a threat in one of the files. Obviously, such a check is potentially dangerous because of the risk of infection of the system, so it is recommended to try installing the same application received from another source.
If the user is told that Windows is notmanaged to install the necessary files, then one of the reasons may be incorrect operation of the installer. Previously, we described the process of installing the application. It happens "under the control" of the executable module, which tells the system which files to move to from the temporary folder, decompresses the compressed data. Therefore, any failure in its functioning just leads to the message "Windows could not install the necessary files". Although, we repeat, this is, just one of the possible options. The solution is to test the operation with a similar application from another source.
Since the installation is done on some kind of disk(hard drive, flash drive, etc.), then if you have enough free space on it, the installation can not be completed without errors. In addition, failures when copying files can be caused by errors in the file system on the media itself. In these cases, you need to make sure that there is enough free space, and also check the disk for errors.
