Whenever I want to install any applications on my Windows 10 computer, shows “error opening file for writing” error. Is there anyone who can tell me the way to solve this problem? Any suggestions will be appreciated.

Things to look at

- Program not compatible with Win10
- Windows 10 in S mode
- other pending installs or previous version of software causing issues
- pending restart needed
- Do not have access rights to folder being changed
- UAC is preventing it somehow
- User profile corrupted.

Thanks for replying. I found this yesterday and running the installer with administrative privileges allowed the installation to complete.

In Windows 10 you may have to run all installers with admin privilege in order to install to your boot drive. It's stupid but welcome to Windows.

If your login is set as an Admin and still have to "run as administrator" then sounds like its UAC (User Access Control) that is causing headaches.

I just turn that off, I found even Corsairs iCue software will sometimes not run right with UAC on.

That could be! I got tired of turning it off. Seems mine turns back on at every update.
