How to update the license remotely with very little effort.  This comes in handy when you have alot of computers over a network with expired or soon to be expired licenses.

You will need the PSexec.exe file on your computer (in my case, saved directly on c:)  Then create a batch file with this following line:   

c:\psexec.exe @computerList.txt -n 15 -c c:\tmp\updatelicense.bat

• The "-n 15" part tells psexec to try to connect to the remote computer for 15 seconds before giving up. 
• The "-c"tells psexec to copy the batch file "updatelicense.bat" to the remote PC before executing it.
• The "@computerlist.txt" is a txt file located in in the c:\tmp folder that includes a list of computer names.

So what is the updatelicense.bat file you ask...here it is :

@echo off
c:
cd "c:\program files\ibm\spss\statistics\19"
licenseactivator.exe `type your license here` (without the quotes)
exit

If you want to update the license on a single computer you can also create a batch file with this line. (no need to create a computer list.txt file).

c:\psexec.exe \\Computername -c c:\tmp\updatelicense.bat
