I have TIA Portal v15.1 uptd4  and Win 10 pro-OS. I am not an expert but curious about Openness possibility. I used Openness open project method before in another project but now I cannot use it anymore. It throws an exception: "The argument path cannot be a specific path". But in the Openness script guide, it is used as a path. I couldn't find where I made a mistake. I would be glad if you help me. You can see the error in the attachment.

hello,

try to open your project with "TIA Openness Explorer":

DEBUG_IDEA: try to open a new empty project...

hello,

try without double backslash in the path "...C:\\..."

Hello, 

I also tried without backslash and it gave the same result.

hello,

I mean:

new FileInfo(@"C:\Users\User\Documents\Project1\Project1.ap15_1")

or

new FileInfo("C:\\Users\\User\\Documents\\Project1\\Project1.ap15_1")

Hallo,

This works, now I realize that the whole error is about writing the wrong path. A small but silly mistake. Thank you very much for your contribution. I am grateful to you.
