Trying to Install Forge-Getting Unsupported Command

[Sazilcat]

Hello.  I'm sure there is something simple I'm not doing, but I am stuck.  I have the latest Java installed, but when I try to install Forge with the installer I get this:

 

Unsupported Command: C:\Users\Kjmyl\Downloads\forge-1.5.2-31.1.37-installer(1)jar

 

Does anyone have an idea as to what I am doing wrong?

I would guess that you spelled the filename wrong. use tab  completion, get to the word forge then hit tab.

I apologize for my lack of tech saavy, but I'm not exactly sure what you are asking me to do.  I click the installer and get the message.  I haven't spelled anything.  Thank you for your reply.

Ah ok, so you typed out the error you got, not a copy/paste.

You should try running it from the commandline. If you're on windows, open the folder the installer is in, hold shift and right-click an empty space to get a menu, and choose open powershell (or command) here. Then type java -jar forge<TAB> (actually press tab, not <TAB>)

It looks like the filename is spelled wrong. Change the 1.5.2 to 1.15.2.

When I opened the window, I was unable to access command or powershell.  It didn't give me the option.  Any ideas why?  What am I doing wrong?

Are you holding down shift on the keyboard when you right-click?

Also, make sure you're not right-clicking on a file.

I was right clicking on a file.  I got into powershell, typed what you wrote, and hit tab.  I'm not sure what to do next.  I'm not trying to be difficult, I'm just really not tech saavy.

It should expand and fill in the whole filename for you.

So I typed java -jar for<TAB> and it autofilled to

java -jar .\forge-1.15.2-31.1.0-installer.jar

[Sazilcat]

That does populate, but I wasn't sure what to do next.  I hit enter and got this:

 

java-jar : The term 'java-jar' is not recognized as the name of a cmdlet, function, script file, or operable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Put a space between Java and -jar

That worked.  Thank you so much for taking the time to help me.  I really appreciate it.
