Error opening file for writing
If you receive this error message, here’s what you need to do.
1] Make sure no other installation is in progress. The easiest way is to restart your computer and try to install the program.
2] If you receive this error even after starting the installation after restarting your computer, select Retry. If it doesn’t work, select Abort and complete the installation. Now go to the folder where you downloaded or placed the setup file and delete it.
3] Then, use Storage Sense, Disk Cleanup Tool or free junk cleaner to delete the contents of the Temporary files folder.
4] Visit the official home page and re-download the installation file to a different location.
5] Make sure you have downloaded the correct setup file for your OS – namely. x64 or x86
6] Restart your computer, log in as administrator. Then right-click on the setup file and select Run as administrator .
This should help.
If this is not the case, then you may need:
- Take responsibility for the folder where you plan to install the application.
- Use Time Machine Permissions to change the permissions for the folder where you plan to install the application.
But before you do either of these two steps, we strongly recommend that you create a system restore point first.
