[path] Windows 7 - Add Path

I need to add a new path (sumatraPDF) on my PATH variable.
I don't know why it does not work...
I think everything is right but when I try to execute sumatrapdf.exe from CMD it cannot find the program.

This is what I did:

The path is correct, I checked it 1000 times.

The idea is use LaTeX with sublimetext and when I save a .text file sumatra has to open and show to me the result. If I want that I have to add the path of SumatraPDF... but it does not work.

In answer to the OP:

The PATH environment variable specifies which folders Windows will search in, in order to find such files as executable programs or DLLs. To make your Windows installation find your program, you specify the folder that the program resides in, NOT the program file itself!

So, if you want Windows to look for executables (or other desired files) in the folder:

C:\PHP

because, for example, you want to install PHP manually, and choose that folder into which to install PHP, then you add the entry:

C:\PHP

to your PATH environment variable, NOT an entry such as "C:\PHP\php.exe".

Once you've added the folder entry to your PATH environment variable, Windows will search that folder, and will execute ANY named executable file you specify, if that file happens to reside in that folder, just the same as with all the other existing PATH entries.

Before editing your PATH variable, though, protect yourself against foul ups in advance. Copy the existing value of the PATH variable to a Notepad file, and save it as a backup. If you make a mistake editing PATH, you can simply revert to the previous version with ease if you take this step.

Once you've done that, append your desired path entries to the text (again, I suggest you do this in Notepad so you can see what you're doing - the Windows 7 text box is a pain to read if you have even slight vision impairment), then paste that text into the Windows text box, and click OK.

Your PATH environment variable is a text string, consisting of a list of folder paths, each entry separated by semicolons. An example has already been given by someone else above, such as:

C:\Program Files; C:\Winnt; C:\Winnt\System32

Your exact version may vary depending upon your system.

So, to add "C:\PHP" to the above, you change it to read as follows:

C:\Program Files; C:\Winnt; C:\Winnt\System32; C:\PHP

Then you copy & paste that text into the windows dialogue box, click OK, and you should now have a new PATH variable, ready to roll. If your changes don't take effect immediately, you can always restart the computer.

Another method that worked for me on Windows 7 that did not require administrative privileges:

Click on the Start menu, search for "environment," click "Edit environment variables for your account."

In the window that opens, select "PATH" under "User variables for username" and click the "Edit..." button. Add your new path to the end of the existing Path, separated by a semi-colon (%PATH%;C:\Python27;...;C:\NewPath). Click OK on all the windows, open a new CMD window, and test the new variable.

I founded the problem: Just insert the folder without the executable file.
so Instead of:

C:\Program Files (x86)\SumatraPDF\SumatraPDF.exe

you have to write this:

C:\Program Files (x86)\SumatraPDF\

Try this in cmd:

cd address_of_sumatrapdf.exe_file && sumatrapdf.exe

Where you should put the address of your .exe file instead of adress_of_sumatrapdf.exe_file.

The path is a list of directories where the command prompt will look for executable files, if it can't find it in the current directory. The OP seems to be trying to add the actual executable, when it just needs to specify the path where the executable is.

I think you are editing something in the windows registry but that has no effect on the path.

Try this:

the variable of interest is the PATH

also you can type on the command line:

Set PATH=%PATH%;(your new path);
