Why can't I start programs in the command line without /d? (Windows 7x64)

Question

I am trying to create a batch script that opens a program. I am doing some testing and I can't figure this out: If I run CMD.exe and input `start /d "C:\wamp" wampmanager.exe` the program opens but If I run CMD.exe and input `start "C:\wamp\wampmanager.exe"` I get "the current directory is invalid" Now when I try to do `start runas /profile /user:Administrator "C:\wamp\wampmanager.exe"` I get prompted for Administrator's password, but nothing happens when I enter it. Can someone please tell me how I can run the above command?

Accepted Answer

Because the start program's syntax expect the window title as its first quoted argument. (see `start /?`). You can supply an empty string, however:

```
start "" "C:\wamp\wampmanager.exe"
```

or, if you don't need quotes to mask parts of the path, just leave them out altogether:

```
start C:\wamp\wampmanager.exe
```
