Indy 10 - IdHTTP.Get raising "Could not load SSL library"

In my application I am using IdHTTP.Get. A part of the code:

var
  IdHTTP: TIdHTTP;
begin
  IdHTTP := TIdHTTP.Create(nil);
  Output := IdHTTP.Get(url);
  ...
  IdHTTP.Free;

Using IdHTTP.Version gives me the version: 10.6.2.5263

I have downloaded the OpenSSL from here, both libeay32.dll and ssleay32.dll are in the same folder of my application.

This problem occured since I am using a new laptop with Windows 10. I hope someone can tell me how to solve this problem!

After trying the various solutions offered here, none of them work with the latest version of Windows 10 or Windows 11. I would like to share my solution that works:

Just install the latest version of open SSL openssl-1.0.2u-x64_86-win64 which is available here.

It includes the two necessary libraries for TidHTTP libeay32.dll and ssleay32.dll in version 1.0.2.21

Having 32 bit target platform for your application in a 64 bit system will also cause this problem. I don't know how to properly fix this but an easy way is to compile exe for same system your OS is.

If you need to access an https url, you must add some code, to complete the creation of the TidHTTP component.

Try use something like this:

// create components
HTTPs := Tidhttp.Create(nil);
IdSSL := TIdSSLIOHandlerSocket.Create(nil);
// try..finally for free
try
  // ini
  HTTPs.ReadTimeout := 30000;
  HTTPs.IOHandler := IdSSL;
  IdSSL.SSLOptions.Method := sslvTLSv1;
  IdSSL.SSLOptions.Method := sslvTLSv1;
  IdSSL.SSLOptions.Mode := sslmUnassigned;
  ...

You need to add IdSSLOpenSSL to uses clause.
