ROOT C++ in Windows

Newbie

Sorry for making this hard and taking your time,

here what I am getting:
C:\Users\abhis>\root\bin\thisroot.bat
The system cannot find the path specified.

22

You have an extra backslash in your command. It should be root\bin\thisroot.bat instead of \root\bin\thisroot.bat.

C:\Users\abhis>root\bin\thisroot.bat
23

ok it ran succesfully

now while running root, it says “‘root’ is not recognized as an internal or external command,
operable program or batch file.”

25

Did you type root after root\bin\thisroot.bat in the same Developer command prompt for vs 2022 session? Probably not…

26

yes, I did that

27

Can you copy and paste the whole session, like I did before, so I can see what you’re doing?

28

C:\Users\abhis>root\bin\thisroot.bat

C:\Users\abhis>root
‘root’ is not recognized as an internal or external command,
operable program or batch file.

C:\Users\abhis>

29

OK, can you copy and paste the output of dir root\bin\*.exe

30

C:\Users\abhis>root\bin*.exe
The system cannot find the path specified.

31

C:\Users\abhis>dir root\bin*.exe
Volume in drive C has no label.

Weird… Then can you start root like this: root\bin\root.exe

33

RegOpenKeyEx(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Kits\Installed Roots\KitsRoot10): returned 2: The system cannot find the file specified.

Still from the Developer command prompt for vs 2022 session? Then I suppose you didn’t install the Desktop development with C++ from the Visual Studio Installer?

35

From the Visual Studio Installer:

37

done! Now where to use this root permanently.

38

You can add a new ROOTSYS environment variable pointing to the location of ROOT (in your case C:\Users\abhis\root) and add %ROOTSYS%\bin in your PATH. If you don’t know how to do this, look for Environment variables in the Windows Settings

39

yeah I know environment variable setting in windows, Now I will add the path C:\Users\abhis\root as the name root., then what to do!

40

No, please follow exactly what I said

Then you should be able to start ROOT from any Developer command prompt for vs 2022 session
