What to do if Windows can not install the required files

According to the latest statistics, the percentage of computer systems running the Microsoft-Windows software suite is about 91%. In light of this, do not be surprised at the abundance of questions from users who are somehow connected with the work of this particular OS. One of the most common ones is related to the peculiarities of the work of the accompanying software. So, sometimes an attempt to install the application results in a "Windows can not install the necessary files 0x80070017" error. Similar failures can be connected either directly with the operating system Windows itself, or with third-party applications.

"Problem" carrier

Although many computer owners have virtually abandoned the use of CDs, preferring media based on solid-state flash memory, still 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.

Incorrect entry

In order for the drive to properly read data from the disc, it is recommended to record at a low speed, down to the minimum. In addition, the program for recording should be properly configured, 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 with AHCI to the IDE in the system BIOS.

Security Lock

Both of the above items relate primarily to errors that occur when the operating system itself is installed on a computer. No less often, users receive a message stating that Windows could not install the necessary files when working with applications. In order to understand the reason for 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, the program creates a complete set of program files 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, if you see something like this, you can try disabling anti-virus protection for the duration of the application installation. If the installation is repeated 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 because of the risk of infection of the system, so it is recommended to try installing the same application received from another source.

Internal damage

If the user is told that Windows could not install the necessary files, one of the reasons may be the 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 performance 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.), 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.
