Hello Helmut,
I am not quite sure about the syntax rules for the set command in BAT-files.
I couldn't find an explicit and detailed description of the handling of
quotes in strings.
Here are 2 examples under Windows7 showing the problem for 2 lines extracted
from copyfiles.bat:
Example 1 (original version of copyfiles.bat with quotes):
C:\>set QMSI_VCREDIST_PATH="c:\Program Files (x86)\Microsoft Visual Studio
12.0\VC\redist\1033"
C:\>copy "%QMSI_VCREDIST_PATH%\vcredist_x64.exe"
Das System kann die angegebene Datei nicht finden.
I have spaces in the path name which I can't avoid. This leads immediately
to the error shown below the copy command line (the file under consideration
exists - see example 2!).
The complete script is rather long and a user can easily fail to notice the
error message.
Example 2 (no quotes):
I drop the quotes (looks of course a bit strange) and run now
C:\>set QMSI_VCREDIST_PATH=c:\Program Files (x86)\Microsoft Visual Studio
12.0\VC\redist\1033
C:\>copy "%QMSI_VCREDIST_PATH%\vcredist_x64.exe"
Zugriff verweigert
0 Datei(en) kopiert.
Everything is now fine - the file under consideration is found. "Zugriff
verweigert" is ok. I do not have write permission to the given directory.
Thus, I think it would be better to remove the quotes in the path setting
commands of copyfiles.bat (and maybe in similar scripts).
Have a nice weekend
Wolfgang
