How can I get the location of .Net framework installation files path from a .BAT file.
Actually I have to use "Installutil" from a batch file.

Any kind of help is welcome.

Good question, taking into account there can be several versions of Framework on the same machine, each in separate directory.
I do something like "%windir%\Microsoft.NET\Framework\v4.0.30319" (I manually go there and then figure out where is what) but I don't think this is a good way.

Your v.2.0 will be found there:
%windir%\Microsoft.NET\Framework\v2.0.50727
It will work.

Sorry I cannot give real answer.

Here is a way to do it in .Net.

VB

Dim a As Reflection.Assembly = Reflection.Assembly.LoadFile(filename)
Dim IUPath As String = "%SystemRoot%\Microsoft.net\framework\" & a.ImageRuntimeVersion & "\InstallUtil.exe"

Sorry, I didn't notice batch file. Let me do a bit work and I'll be back to you.

[Edit]
Oh man! Here is your solution. Sorry for misunderstanding your question at first.
You now just have to change the %PROG% or pass it as parameter.

Hope this helps.
And yes, %FIRSTPART%%DOTNETVER%%SECONDPART% gives you the path of InstallUtil.

@echo off

SET PROG="YourServiceHere.exe" 

SET FIRSTPART=%WINDIR%\Microsoft.NET\Framework\v
echo %FIRSTPART%
SET SECONDPART=\InstallUtil.exe
SET DOTNETVER=4.0.30319
echo %FIRSTPART%%DOTNETVER%%SECONDPART%
IF EXIST %FIRSTPART%%DOTNETVER%%SECONDPART% GOTO install 
SET DOTNETVER=3.5 
IF EXIST %FIRSTPART%%DOTNETVER%%SECONDPART% GOTO install 
SET DOTNETVER=3.0 
IF EXIST %FIRSTPART%%DOTNETVER%%SECONDPART% GOTO install 
SET DOTNETVER=2.0.50727 
IF EXIST %FIRSTPART%%DOTNETVER%%SECONDPART% GOTO install 
SET DOTNETVER=1.1.4322 
IF EXIST %FIRSTPART%%DOTNETVER%%SECONDPART% GOTO install 
SET DOTNETVER=1.0.3705 
IF EXIST %FIRSTPART%%DOTNETVER%%SECONDPART% GOTO install 
GOTO fail 
:install 
ECHO Found .NET Framework version %DOTNETVER% 
ECHO Installing service %PROG% 
%FIRSTPART%%DOTNETVER%%SECONDPART% %PROG%
GOTO end 
:fail 
echo FAILURE -- Could not find .NET Framework install :param_error 
:end 
ECHO DONE!!!
