I am working on a long path support for an application. The problem is, I cannot even start the program: when I place it on a path longer than 260 characters, I get this pop-up error when starting it:
The application was unable to start correctly (0xc0000106). Click OK to close the application.
I have enabled long path support as described here and I can confirm that at least some programs can open files on paths over the limit. But opening files is not enough, I need to actually start the program at such long path. How can I do that?
