Not able to install Photoshop

Hello,

I am trying to install photoshop on macOS Catalina 10.15.1

The Photoshop Installer stops to downlaod at 4.8% There is no firewall active or a virus scanner.

So I've tried to install it with the full package: AdobePhotoshop20-mul.dmg .. but this failed as well with error code 1

The last lines in the HDInstaller.log are:

11/16/19 19:48:04:985 | [INFO] | 934 | Bootstrapper | OOBEUtils | CommBridge | | OOBEUtils | 10348 | Pipe 5 is closed on other end or is invalid

any help would be appreciated!
