If when running a setup file for installing the software you receive message Error opening file for writing on your Windows 10/8/7 then this post will help you fix the problem. This can occur when running a setup file for installing a program and commonly occurs for Steam, VLC, MSI Afterburner, GlassWire, Notepad++, OBS, Mod Organizer, WinpCap, FileZilla, NSIS, QBitTorrent, Kodi, Wireshark, BSPlayer, rtcore64, GWCtlSrv.exe, qt5core.dll, vcredist_x86.exe, npf.sys, etc.
Error opening file for writing
If you receive such an error message, here is what you need to do.
1] Ensure that another installation is not in progress. The easiest way is to restart your computer and try to install the program.
2] If you receive this error even after you start the installation after restarting the computer, then select Retry. If it does not work, select Abort and terminate the installation. Now navigate to the folder where you downloaded or placed the Setup file and delete it.
4] Visit the official homepage and fresh download the setup file to a different location.
5] Ensure that you have downloaded the correct setup file for your OS – viz. x64 or x86
6] Restart your computer, sign in as administrator. Next right-click on the setup file and select Run as administrator.
This should help.
If it doesn’t, then you may need to:
- Take ownership of the folder where you are planning to install the application.
- Use Permissions Time Machine to change Folder permissions for the folder where you are planning to install the application.
But before you do either of these two, we strongly recommend that you create a system restore point first.
