Cannot install into c:\Program files on Windows 7

I have an installer written in Java using Izpack. It works OK on Windows XP, however on Windows 7 it cannot write to c:\Program Files. Strangely enough, as a user running this 开发者_C百科installer I can create folders under c:\program files, but not from the installer itself.

What am I missing ?

in order to write to this path, the installer would need to ask for and been granted run as adminsitrator privledges.

For Java: Run the CMD prompt as admin or powershell as admin and navigate to JAVA's Bin dir....and run java.exe -jar #Full path of your jar file# that will get it the privledges

Add

<run-privileged/>

to the info part of your installer.xml.

For example::

<info>
    <appname>IzPack</appname>
    <appversion>4.2.0</appversion>
    <authors>
        <author email="" name="Julien Ponge (project founder)"/>
        <author email="" name="The fantastic IzPack developers and contributors"/>
    </authors>
    <url>http://izpack.org/</url>
    <javaversion>1.5</javaversion>
    <requiresjdk>no</requiresjdk>
    <run-privileged condition="izpack.windowsinstall.vista|izpack.macinstall"/>
    <summarylogfilepath>$INSTALL_PATH/installinfo/Summary.htm</summarylogfilepath>
</info>

You need to run the installer as admin. Only admin can write to the Program Files directory. Usually when a user tries to make changes, the UAC asks if you're sure. This isn't necessarily true for a program.

Have you tried with Run As... Administrator option ?

1. Run cmd with administrative privileges
2. java -jar ***.jar
