If you're still in this code, let me expand on the topic with some explanations.
-----------------------------------------------
The main code is here:
@Zanzer: https://forum.cheatengine.org/viewtopic.php?t=597759
-----------------------------------------------
1) Make sure the URL will download the current trainer.
2) Upload your updates to a site that will always use the same URL.
3) Define a path for the current Trainer.

Code:
local path = TrainerOrigin or getMainForm()


4) If you are going to download the new version to a different location, identify it as well.

Code:
local path1=[[D:\downloader]]
local name = path1 .. "\\" .. newName


5) Create another url for version test and Trainer name.

Code:
local versionNum = 0
local ExVersion = 01
local newName=""
UDF1.CEButton1.Caption="Download"

local path = TrainerOrigin or getMainForm() --Ex Trainer path..
local path1=[[D:\downloader]] --New Trainer path..

function loadUrl(link33)
  local int=getInternet()
  s=int.getURL(link33)
  int.destroy()
  return s
end

function VersionCheck()
local result = loadUrl("https://docs.google.com/document/d/1_Px-WKrnyw8MsqmwJnz2__eufO6cey653n77VZTDEok/export?format=txt")
local SL1 = createStringlist()
SL1.Text=result
for i=0, strings_getCount(SL1)-1 do
versionNum=SL1[1]--:sub(1,9)
newName=SL1[2]
versionNum=tonumber(versionNum)
ExVersion=tonumber(ExVersion)
end
SL1.destroy()
if versionNum==ExVersion then
UDF1.CEButton1.Enabled=false
else
showMessage("There is a new version.\nClick the 'Download' button to download!")
UDF1.CEButton1.Enabled=true
end
end

VersionCheck() --Open Trainer.. Execute func..

local name = path1 .. "\\" .. newName

function TrainerUpload()
if syntaxcheck then return end
local TABLE_VERSION = tonumber(ExVersion)
local table_url = "https://docs.google.com/uc?export=download&id=1d-lCWA1fAEpkPDTxvjGu4dxgNSRCj1E0"
local http = getInternet()
  local version = tonumber(versionNum)
  if version > TABLE_VERSION then
    local answer = messageDialog("There is a newer version of this table.\nWould you like to download it now?", mtWarning, mbYes, mbNo)
    if answer == mrYes then

      messageDialog("Caution:\nThis update will permanently delete the old version.\nIf you do not want to delete the old version,\nget a copy before you approve!", mtInformation, mbOK)
      local latest = http.getURL(table_url)
      if latest ~= nil then
        local file = io.open(name, "wb")
        file:write(latest)
        file:close()
       local name = os.execute(name, "\\"..newName);
       --local file = os.remove(ExName)
        --closeCE()
        loadTable(name)
      else
        messageDialog("Failed to load the new table!", mtError, mbOK)
      end
    end
  else
    messageDialog("You currently have the latest version!", mtInformation, mbOK)
  end
--else
 -- messageDialog("Failed to find latest version!", mtError, mbOK)
--end
http.destroy()
--  int.destroy()
assert(true)
end

UDF1.CEButton1.OnClick function()
TrainerUpload()
end


Note: For ".exe" files, remote invocation may fail due to possible security errors in the installation and run procedures. My recommendation; Use the above code with ".CT" or ".Cetrainer".
