cmd PATH error - \\common was unexpected at this t

问题:

i am adding a line in a .bat file look like this:

path %~dp0;%PATH%

But this message is shown:

\common was unexpected at this time.

Let me show you the path.

PATH=C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program File
s (x86)\Common Files\Microsoft Shared\Windows Live;c:\Program Files (x86)\AMD AP
P\bin\x86_64;c:\Program Files (x86)\AMD APP\bin\x86;C:\Windows\system32;C:\Windo

m Files\Intel\WiFi\bin\;C:\Program Files\Common Files\Intel\WirelessCommon\;C:\P
rogram Files (x86)\Common Files\Thunder Network\KanKan\Codecs;C:\Program Files\C

This is the path. The path i want to add (%~dp0) is:

C:\Users\Workspace\Desktop\Files\Programming\GoogleSearch\

This is important for me.
Thank you.

It seem to be the issue described in this article. You probably use command language construction with parentheses in your batch-file.

Related to this post (tested)

• Remove %PATH%variable in your set PATH=.. string.
• Like set PATH=C:\Path\to\file instead of set PATH=%PATH%;C:\Path\to\file
