There are different approaches.
If it is a registered software you could have a look to your registry (HKEY_LOCAL_MACHINE\SOFTWARE) to figure out if a software is installed. See also http://www.dostips.com/DtCodeCmdLib.php#Function.IsRegKey.
Otherwise you could look for a special exe file or folder. E.g.

Code: Select all

@echo off &setlocal
set "dotNETpath=%SystemRoot%\Microsoft.NET\Framework\v3.5"

if exist "%dotNETpath%" (
  echo Dot net frame work 3.5 is installed.
) else (
  echo Dot net frame work 3.5 not found.
)

pause

I've had most success querying for installed software by going through hklm\software\microsoft\windows\currentversion\uninstall
This has a list of installed software and keys that give info on the displayname,version, install location etc.

try using the reg command and output the results. IE

Code: Select all

REG QUERY \\machine\hklm\software\microsoft\windows\currentversion\uninstall >>output.log

sxekjb is right, this is also a possible solution.
The first you have to do is allways searching for a meaningful key in the registry. Use any registry editor (e.g. regedit.exe).

If you want to use the function of my url:

Code: Select all

@echo off &setlocal

call :IsRegKey "HKLM\SOFTWARE\Adobe\Acrobat Reader" &&(
  echo Acrobat Reader is intalled.
)||(
  echo Acrobat Reader is Not intalled.
)

pause
goto :eof

::~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
:IsRegKey Key -- succeeds if Key exists
::            -- Key  [in]  - registry key
:$created 20060101 :$changed 20080219 :$categories Registry
:$source http://www.dostips.com
reg query "%~1">NUL 2>NUL
EXIT /b

The return of the function is something like TRUE or FALSE (errorlevel is 0 or greater than 0).
This example is for "Acrobat Reader". Of couse you have to replace and append the function calls with your keys.
