Application is unable to write to the following location

[b_easy]

Hi,
got an issue with Aftershot 3 after installing.
I cannot open the application due an error: Application is unable to write to the following location. Please check permissions and free space.
I have 760GB free of space, I am also the administrator of this computer so it has to do with sometjhing else.
I tried to reinstal the program and restart the computer but all my actions failed.

Have any of you had such kind of problem?
