283 g of hard disk space available

Downloaded trial version twice

Rebooted

Run as Administrator

Cleared windows temp files

All help will be appreciated.

Welcome to the Serif Affinity forums.

Your SetupUI.log file has this error message:

+Error: Error writing to file: C:\Program Files\Affinity\Designer\d3dcompiler_47.dll.   Verify that you have access to that directory.

When you say you've run as Administrator, do you mean that:

1. You're installing using an account that has Administrator authority?
   or
2. You right-clicked on the executable and chose Run as Administrator?

For users that have this problem, #2 will work in cases where #1 doesn't.

Thanks Walt.  I am using an administrator account and I'd also  tried using the "run as administrator" option.

Turns out my antivirus software - 360 Total Security - was blocking the installation without any notification or anything.  Not good.  Now I'm going to look for better antivirus software.

Affinity Designer has now installed and runs.  Now the fun begins!

Thanks again!

Hello @EarlD,

You don't need to install any extra antivirus software! Microsoft Defender has been one of the best antivirus solutions for years.

Now that came as a big surprise to me.
When I read what you said I thought, “Nah, that can’t be true... can it?”.
Then I read the information in the website and it’s very interesting.
I think I need to do more looking around about this.

With every additional external application that operates with increased system rights, a possible gateway for malware is created.
If any component in the additional application is faulty, criminals could possibly use it to inject malicious code.
