New to AutoIT, need help scripting...

[MadzKeen]

I'm trying to write a program that will update a client application. It first needs to check to see if the old license file is present and delete it. Second it need to check if the upgrade as already been done and call in a module that will run the installation part of it if it isn't already installed. I'm so lost so any help would be great. My code is list below: (It sucks I know.)

'Check to see if the old license file exist, if so delete it

if "c:\evrsi.sys" True

then delete "c:\evrsi.sys"

Else

if "C:\Windows\Program Files\Rockwell Software\Factory Talk Activation\ftactTool.exe" True

then install FASU

Else

EndFunc

' Installing the Factory Talk Activation Software Module

Install "C:\Windows\Program Files\Rockwell Software\Factory Talk Activation\ftactTool.exe"
