Using Psexec to silently install Firefox on multiple workstations

by on Sep.24, 2009, under Windows Info

Recently, I needed to install Firefox-3.5.3 on multiple workstations in an Active Directory domain. Rather than create MSI packages and assign the application with Group Policy, I used Psexec and batch scripts to push it out. Here’s how:
If you don’t have Psexec installed, you can download it from Microsoft here: http://technet.microsoft.com/en-us/sysinternals/bb896649.aspx
Next, download the installer you want to use. In this example, we’ll use Firefox. Make a share on your server that all users can read, and place the installer inside the share.
So now, we’ve got \SERVERNAMESHARENAMEFirefoxInstaller.exe
Next, you need a few files to make this happen:
1. UpdateClients.bat
2. hostnames.txt
3. SoftwareInstaller.bat
All of these files need to be in the same directory, and you must have administrative privileges on the workstation you wish to update.
Basically, the UpdateClients.bat file enumerates the hostnames.txt, and passes the hostnames of the workstations/servers found in it to the SoftwareInstaller.bat file. Here are the contents of the files:

1. UpdateClients.bat


for /f "tokens=*" %%a in (hostnames.txt) do SoftwareInstaller.bat %%a

2. hostnames.txt (one hostname per line)


hostname1
hostname2
hostname3

3. SoftwareInstaller.bat


SET SERVERNAME=replacewithservername
SET SHARENAME=replacewithsharename
echo "checking for Installers directory on the target..."
if not exist \%1C$installers mkdir \%1C$installers
if not exist \%1C$installersfirefox353 mkdir \%1C$installersfirefox353
echo "copying Firefox install to install directory..."
xcopy "\$SERVERNAME$SHARENAMEFirefoxInstaller.exe" "\%1C$installersfirefox353" /e /y
echo "Installing Firefox..."
psexec.exe \%1 "c:installersfirefox353Firefox353.exe" -ms
echo "Firefox Done."

Now, fill the hostnames.txt with your hostnames, and double-click UpdateClients.bat.
