Raspberry BOOM

OK - so I repeated the install and it seemed OK (as before) but I got the same error message. For fun, I tried several of the obspy exe programs and they all yield the same result.

(obspy) C:\Users\Ken>obspy-runtests
Fatal error in launcher: Unable to create process using '“d:\bld\obspy_1593448028650_h_env\python.exe” “C:\Users\Ken\Anaconda3\envs\obspy\Scripts\obspy-runtests.exe” ': The system cannot find the file specified.

(obspy) C:\Users\Ken>obspy-scan.exe
Fatal error in launcher: Unable to create process using '“d:\bld\obspy_1593448028650_h_env\python.exe” “C:\Users\Ken\Anaconda3\envs\obspy\Scripts\obspy-scan.exe” ': The system cannot find the file specified.

(obspy) C:\Users\Ken>obspy-plot.exe
Fatal error in launcher: Unable to create process using '“d:\bld\obspy_1593448028650_h_env\python.exe” “C:\Users\Ken\Anaconda3\envs\obspy\Scripts\obspy-plot.exe” ': The system cannot find the file specified.

Looking at python in my Windows programs, I seem to have version 2.7 and 3.7 installed. If I search for “python.exe” I find only version 2.7, and it is located in:

d:\python27\

so Anaconda is on drive C: and python is on drive D:

If that is a problem:

Is there a way to specify that arrangement? or do I have to uninstall/reinstall something?

Thanks
