No aspx pages need to be replaced.
All the premium tools can be run standalone, you only have to replace the service (attached instructions)
Take a look at the current name of your service (should be lansweeper32.exe,lansweeper32.exe or lansweeper32.exe)
Steps to upgrade
1) Rename Lansweeper32.exe to (your existing filename)
2) Stopped the service
3) Copied lansweeperxx.exe over of existing file
4) Add the following line to your .exe.config file (after the line with listenport)
<add key="Activescanning" value="1" />
5) Start the service
You can enable and disable active scanning with the 1 - 0 parameter
Your config file should look something like this
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
<add key="ConnectionString" value="Persist Security Info=False;Data Source=myserver\sqlexpress;Initial Catalog=Lansweeper;User ID=lssqluser;Password=mysecretpassword" />
<add key="ConcurrentThreads" value="10" />
<add key="ListenPort" value="9524" />
<add key="Activescanning" value="1" />
</appSettings>
</configuration>
