Quite Mode:
- Create a script which executes the too= l in quite mode - a snippet is shown below:
|
64 bit: =
.... =
set
errorlevel=3D =
C:\HAVTool\sources\amd64\havtool.exe
/q =
echo
%ERRORLEVEL% =
.... |
|
32 bit: =
.... =
set
errorlevel=3D =
C:\HAVTool\sources\i386\havtool.exe
/q =
echo
%ERRORLEVEL% =
.... |
Note: Launch the scrip= t from an elevated prompt.
Log Option:
To generate richer logs, based on your OS architecture= , run one of the following commands from an elevated command prompt:
c:\HAVTool=
\sources\i386\havtool.exe /=
log
%temp%\HAV.txt
= or
c:\HAVTool=
\sources\amd64\havtool.exe
/log %temp%\HAV.txt
