According to the latest statistics, the percentage of computing systems running the Microsoft software package - Windows, is about 91%. In light of this, one should not be surprised at the abundance of questions from users who are somehow related to the operation of this particular OS. One of the most common is precisely related to the features of the work of related software.
So, sometimes an attempt to install the application leads to the error "Windows cannot install the necessary files 0x80070017." Such failures can be associated both directly with the Windows operating system itself, and with third-party applications.
"Problem" carrier
Although many owners of computers have almost abandoned the use of compact discs, preferring media based on solid-state flash memory, still the first are still found. One of their drawbacks is the impossibility of error-free reading of recorded data during inaccurate storage and scratches on the mirror surface. Thus, if when working with CDs when trying to install the application, a system window appears stating that Windows cannot install the necessary files, you need to make sure that there is no damage to the media. Sometimes, in order to restore working capacity, it is enough to wipe the disc, removing dirt, fingerprints, etc.
Invalid entry
So that the drive can read data from the disk normally, it is recommended to record at a low speed, up to the minimum.
In addition, the recording program must be properly configured, so the various functions of "re-burning" must be disabled. And finally, it should be remembered that rewritable
compact discs (RW) are inferior in quality to their simpler counterparts of the R standard (both + and -). The best option for "treatment" is the use of a flash drive. You can also try switching the operating mode of the hard drive from AHCI to IDE in the system BIOS.
Security Lock
Both of the above points relate primarily to errors that occur when installing the operating system itself on the computer. No less often, users receive a message that Windows could not install the necessary files when working with applications. To understand the cause of what is happening, we will generally consider the process of installing programs. When you click on the executable file, background data is extracted into the intermediate folder, from which, like bricks, an integral set of program files is created in the target directory. If anti-virus protection is installed on the computer that has detected a danger in one of the unpacked files, then access to it will be 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 reinstallation fails without errors, then the reason is in the antivirus or, indeed, in the presence of a threat in one of the files. Obviously, such a check is potentially dangerous due to the risk of infection of the system, therefore, it is recommended to try installing the same application received from another source.
Internal damage
If the user is informed that Windows could not install the necessary files, then one of the reasons may be the incorrect operation of the installer. Earlier, we described the application installation process. It takes place “under control” of the executable module, which tells the system which files to transfer to from the temporary folder, and 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 health with a similar application from another source.
Storage device
Since the installation is carried out on some kind of disk (hard drive, flash drive, etc.), when the free space on it is exhausted, the installation cannot be completed without errors. In addition, file copying failures may be caused by file system errors 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.
