[SOLVED] Is there a way to read the system's information in Inno Setup

Is there a way to read the system's information in Inno Setup

Is there a way to read the system's information in Inno Setup, during installation (just at the welcome wizard page)?

By this I mean:

RAM
OS
CPU
user
IP
MAC adress.

It would be a good thing to know. I would like to put this information in say a text document that I would save on my computer. I cannot seem to find material on this online at all, and was hoping if anyone had experience with this, could help?

Solution

There are many different ways to retrieve all these information.

But one universal way to retrieve all of them is a WMI query. It's easy to use in Inno Setup with IDispatch COM automation code.

WMI classes that will interest you are:

function WbemQuery(WbemServices: Variant; Query: string): Variant;
var
  WbemObjectSet: Variant;
begin
  Result := Null;
  WbemObjectSet := WbemServices.ExecQuery(Query);
  if not VarIsNull(WbemObjectSet) and (WbemObjectSet.Count > 0) then
  begin
    Result := WbemObjectSet.ItemIndex(0);
  end;
end;

procedure CollectInformation;
var
  Query: string;
  WbemLocator, WbemServices: Variant;
  ComputerSystem, OperatingSystem, Processor: Variant;
  NetworkAdapters, NetworkAdapter: Variant;
  IPAddresses: array of string;
  I, I2: Integer;
begin
  WbemLocator := CreateOleObject('WbemScripting.SWbemLocator');
  WbemServices := WbemLocator.ConnectServer('.', 'root\CIMV2');
  
  Query := 'SELECT TotalPhysicalMemory, UserName FROM Win32_ComputerSystem';
  ComputerSystem := WbemQuery(WbemServices, Query);
  if not VarIsNull(ComputerSystem) then
  begin
    Log(Format('TotalPhysicalMemory=%s', [ComputerSystem.TotalPhysicalMemory]));
    Log(Format('UserName=%s', [ComputerSystem.UserName]));
  end;
  
  Query := 'SELECT Caption FROM Win32_OperatingSystem';
  OperatingSystem := WbemQuery(WbemServices, Query);
  if not VarIsNull(OperatingSystem) then
  begin
    Log(Format('OperatingSystem=%s', [OperatingSystem.Caption]));
  end;

  Query := 'SELECT Name FROM Win32_Processor';
  Processor := WbemQuery(WbemServices, Query);
  if not VarIsNull(Processor) then
  begin
    Log(Format('Processor=%s', [Processor.Name]));
  end;
  
  Query :=
    'SELECT IPEnabled, IPAddress, MACAddress ' +
    'FROM Win32_NetworkAdapterConfiguration';
  NetworkAdapters := WbemServices.ExecQuery(Query);
  if not VarIsNull(NetworkAdapters) then
  begin
    for I := 0 to NetworkAdapters.Count - 1 do
    begin
      NetworkAdapter := NetworkAdapters.ItemIndex(I);
      if (not VarIsNull(NetworkAdapter.MACAddress)) and
         NetworkAdapter.IPEnabled then
      begin
        Log(Format('Adapter %d MAC=%s', [I, NetworkAdapter.MACAddress]));
        if not VarIsNull(NetworkAdapter.IPAddress) then
        begin
          IPAddresses := NetworkAdapter.IPAddress;
          for I2 := 0 to GetArrayLength(IPAddresses) - 1 do
          begin
            Log(Format('Adapter %d IP %d=%s', [I, I2, IPAddresses[I2]]));
          end;
        end;
      end;
    end;
  end;
end;

It will get you information like:

TotalPhysicalMemory=12835962880
UserName=domain\martin
OperatingSystem=Microsoft Windows 10 Home
Processor=Intel(R) Core(TM) i7-3630QM CPU @ 2.40GHz
Adapter 1 MAC=11:51:67:D0:10:21
Adapter 1 IP 0=192.168.78.2
Adapter 1 IP 1=ef08::8da9:601e:3f8a:da00
Adapter 2 MAC=80:06:E6:10:F7:B9
Adapter 2 IP 0=192.168.1.3

To see all available information in involved classes, run this on command-line:

wmic os get * /format:value
wmic cpu get * /format:value
wmic nicconfig get * /format:value
