Problem with Hex File Upload (XMC1200, Dave4)

Hello, I do need help,

I have some Dave4/3 projects that's works well.

But sometimes when I try to flash my XMC1200 I got an error "There is now file..".
In that case I have to build a new project and have to copy all files from the old project into the new project.
Than I can flash my controllers again.
There is the same problem when I import a project (made on my pc) on an other pc.

There are any path links into the project?

Thanks and regards,

Bernd
