I've had an issue since Monday with all of my Affinity Apps. To start with launching Publisher got an error message that it couldn't start because VCRUNTIME140_CLR0400.dll couldn't be found. None of the apps would open & got the same message. I found & replaced the file but it them wouldn't start because UCRTBASE_CLR0400.dll couldn't be found. I replace that file but the apps still wouldn't launch. To cut a long story short, I uninstalled Publisher & re-downloaded the latest version. But now the installer won't run! I get the initial box asking if I want to install the program but after clicking OK it doesn't do anything. Any ideas? It only seems to affect the Affinity apps. All my other programs are working ok including PagePlus. I don't know what lead to those dll files going missing. It's possibly a Windows thing but I've tried recovering to an earlier date & reinstalling the latest Microsoft Visual C++ redistributables but nothing changes anything. Any help gratefully received.
