Why is Chrome not installing on Windows 10
Chrome's inability to install on Windows 10 is usually caused by incompatibility in the system version, installation program exceptions, permission restrictions, or other environmental problems. 1. System version incompatible: Check and upgrade Windows to the latest version, or use a compatible old version of Chrome. 2. The installer is corrupted or intercepted: re-download the installation package, close the antivirus software/firewall, and run the installer as an administrator. 3. Insufficient permissions or UAC restrictions: Confirm the account to be an administrator, adjust UAC settings or repair registry permissions. 4. Other issues include insufficient disk space, browser conflicts or group policy restrictions. Remaining files need to be cleaned, freed up space or contacted to handle it. In most cases, restart the system, replace the network, or download it again
