All the software on the computer cannot be installed, and every time it says that the files cannot b

1. If this prompt appears when installing the software, the first possibility is that the software itself is damaged or incomplete, and you can try to change the installation disc if it is an installation CD.

2. Many of the contents in the cab are protected and compressed in a non-universal encoding format, so they cannot be decompressed normally, and only the corresponding installer can be called normally. Try installing Microsoft Windows and give it a try.

3. If this prompt appears after the antivirus software checks and kills the virus, it means that the file is damaged by a virus or there is a virus occupying memory space, or the virus is reading and writing the cab file for protection, please try to enter the safe mode to manually delete the virus and cab file file, it is the system cab file, if there is a computer with the same configuration can find it from other computers and copy it back to its original location, you can try to re-file the relevant cab file.

4. If this prompt only appears when extracting large cab files, it means that the system memory may not be properly allocated, first of all, make sure that the physical memory is enough for the system and related software to call, not too small, and secondly, the virtual memory should be reasonably allocated in size. For example, 98 or winme system installed large memory and this prompt appears, in fact, it is not that your memory is not enough, but that your memory is too large to be allocated, if you are two 256m, try to unplug one, maybe it can solve the problem unexpectedly; If this prompt appears on an NT or XP system, please try to defragment a partition with a large amount of free space, and then transfer the virtual memory to this partition, so that you don't have to reinstall the system to solve the problem. If the virtual partition is already in the partition with the largest remaining space, transfer it to another partition and then back as described above.

Why do you have to "first" defragment a partition with a large amount of free space, and then "then" transfer virtual memory to that partition? Because a virtual partition is preferably a contiguous full disk space, if there is disk fragmentation in it, the file allocation mapping table will be out of order, and it is easy to indicate that there is no memory.

5. The system file is missing or incorrect. It is usually recommended to reinstall the system on the Internet, but I don't recommend this, why do you have to shoot the system for a small problem, and besides, the delay in reinstalling the system is not counted, and the work of reinstalling so much software is unbearable. You may wish to transfer the virtual memory according to the above method first, and then proceed to the system repair and installation method if it does not work.

If all the software on the computer cannot be installed, there is probably a problem with the system, and it is recommended to reinstall the system.

In some cases, it cannot be installed due to incomplete software, or the lack of associated software, dynamic link library, or security monitoring software. Here are a few things you can try:

This can happen if there is a problem with the registry or some files are missing.

Close the anti-virus software and security monitoring software first, and then start the security monitoring software after installing the software.

It will be easier to reinstall the system. Newly installed systems generally do not suffer from this problem.

If you have difficulty in operating, you can find someone to help. Or ask 360 Guard's remote operation to help solve the problem.

System Problems Reinstall

When installing the software on the computer, it always displays: Extraction: Unable to write to the file is caused by a setting error, and the solution is:

1. First of all, you need to use "win+r" to open and run.

2. Next, type "cmd" and press enter.

3. Type "chkdsk c: f" and press enter.

Here it is assumed that the C disk is wrong, and the corresponding disk letter can be replaced with other disks).

4. Open "Local Users and Groups" in the window that opens.

5. Open "Users" on the right side.

6. Remove the "account disabled" checkbox. After logging out of the computer, you can change the administrator account.

Hello, if the computer always shows extraction: unable to write files when installing software, one possibility is that the remaining space of the C drive is insufficient, because the system often needs to go through a temporary folder during the installation process, and the temporary folder is generally on the C drive.

You can click Scan Junk in the Clean Junk tab of Tencent PC Manager, and click Clean Now after the scan is complete. If you have installed some software on the C drive, you can also select the software to move in the toolbox of PC Manager, wait for the space occupied by each software to be calculated in the installed software, select a software that is not running, click to select the location, and then click the Start Move button to move.

If you feel that the free space is still insufficient, you can right-click on my computer (win7 is a computer), select properties, win7 needs to click on advanced system settings, click the "settings" button next to performance in the "advanced" tab, and then click change under the virtual memory in the "advanced" tab, select other partitions, select the size of system management, or select custom, click settings. Then select the C drive, select No paging files, and click Settings to restart. If you are Win7, please note that the Automatically manage paging file size for all drives check box at the top is cleared.

Also, move the files on your desktop to a different partition to free up a lot of space. If you are win7, you can also search for cmd in the start menu, right-click on the search results, select run as administrator, and enter powercfg -h off in the pop-up command prompt window to disable the system hibernation function, which can also free up hard disk space equal to the size of physical memory.

This problem may also be caused by insufficient permissions. Please note that if you are still logged in to the system as an administrator, you can right-click on the corresponding section, including the temporary folder and the installation folder, select Properties, click Advanced in the Security tab, double-click an admin user in the "Owner" tab to set it as the owner, and check Replace the owner of sub-containers and objects. If it is win7, you need to click a button to change it.

Then set the permissions for full control for the admin user in the Permissions tab and OK.
