Cannot Install Terragen 4 In Windows 10

[Clintongilliam]

Hell friends. Due to some unknown issues, unable to install Terragen 4 on my Pc it shows an "error opening file for writing" error. I don't know why this is happening and how to fix it. If anyone provides any suggestions it would be greatly appreciated.

So, I searched around online and found this. Tried the troubleshooting mentioned and the issue is solved. Starting the installer as administrator allowed the installation to complete.

Hi Clinton, welcome to the forums.

Curiously, what version of Windows 10 do you have? I don't remember my installers being Admin Rights privileged (the little shield icon) and have been able to install the software. I wonder if it's a specific build issue/security thing. Or maybe that installer itself has changed. They usually come with a sha1 signature which seems to allow TG executables to run without needing to be unblocked or admin rights. There is a read/write issues notified under the signature, however. Maybe it's something to do with that.

Don't make a habit of allowing admin rights to files from the web, especially not from secure addresses (HTTPS). Though I will totally vouch to Planetside Software being safe if you're visiting their SSL secured website(s).
