Helicon Focus 9.0.3 is not starting

Hello,

I'm using Helicon Focus 8.3.11. All is working very well.

Now I want to try Helicon Focus 9.0.3 Beta. The installation is ok. After installation, I will start/open Helicon Focus 9, but nothing happens.
SSD is working for 1-2 seconds. That's it. There is nothing. No failure, no windows. Absolutely nothing.
In Task Manager, there is no Helicon Focus running.

Any ideas?

Kind Regards,
Astrophytum

Hello,

No idea at the moment. Please open the folder C:\Users\<your username>\AppData\Local\HeliconFocus, compress the contents of the whole folder to zip and mail it to us: [email protected]. You can paste this into the address bar of the File Explorer to open that folder directly: %localappdata%\HeliconFocus
