When I try to set up Visual Studio 2017 with R Tools in Power BI Desktop, the R home directory is not detected automatically and I don't know how to choose my "preferred R home directory", or how to find my preferred R IDE (also not detected automatically.) When I try to browse to the C drive to drill down, it is not an option. When I set up a network drive, it tells me the path wasn't identified as a a valid R home Directory. How do I set up a "valid R home directory"? I work on a thin client with Citrix. Is that the problem, and if so, is there anything I can do about it?
