不是内部或外部命令、可运行的程序或批处理文件

Question

I'm trying to call an external function from Python: the function is vboxmanage.exe and I'm accessing it via subprocess call. The problem is that call cannot find the vboxmanage.exe program, even though it is listed in the path variable. I have tried every possible combination, with path, without path, with listing the full director, without listing the director, but call never finds it: vboxmanage is not recognized as an internal or external command, operable program or batch file.

Here my questions:

1. For what reason does call disregard my path variable while in the Windows 10 commend prompt the path variable works fine? I'm using shell=True, so this shouldn't happen.
2. Why is it not possible to specify a path of a program and have it executed like that from the command prompt (assuming it's not in path variable). This used to work under DOS a long time ago, but not in Windows 10. Ie when I type in the command prompt "c:\\Program Files....\\vboxmanage.exe" it won't find the program. I have to first go into the directory and the execute it.
3. Is there a way to manually navigate into the directory via call command and then invoke a second call command to open vboxmanage.exe?

from subprocess import call
param="c:\\Program Files\Oracle\VirtualBox\\vboxmanage controlvm MacBook keyboardputscancode "+h
print (param)
call([param], shell=True)

Answer 1

Just go to these folder: C:\\Program Files\\Oracle\\VirtualBox and copy all the files there and then paste them in this folder: C:\\Users\\username\\VirtualBoxVMs\\Ubuntu64 which contains the .VDI files. Then open command prompt and navigate to this folder: C:\\Users\\Username\\VirtualBoxVMs\\Ubuntu64 and run your command from there and it will be recognize.
