There are probably still a couple of bug fixes and lots of performance improvements to be done. Until then new features are lower priority.

No problem: HKEY_CURRENT_USER\Software\Raabe Software\MMX\14.0

Known problem. Current workaround is to temporarily rename your v14 registry key, so that v15 will not see it.

Have you actually saved the changed layout?

I once wrote a tool for that: https://uweraabe.kilnhg.com/Code/Community/Delphi/CompressPath

The new PngComponents version 1.6.0 with Delphi 10.4 Sydney support is available on GitHub: https://github.com/UweRaabe/PngComponents While the version delivered with GetIt is still on 1.4.0, the above version f.i. supports the new feature of linking to a TPngImageList by ImageName in addition to ImageIndex.

There is an option (checkbox) that the theme follows the Windows theme. Try to switch that off.

The license text inside ELC stays the same. The list in License Manager after importing the new slip file should show 10.4 Sydney.

By magnitudes

Open the ELC web interface and go to License Hosting. Enter your credentials and the certificate as given by Embarcadero. Click Host Licenses. Select the proper license and again click Host Licenses. Got to Licenses. Click on License Files and download the slip files (zipped). Extract the named license slip file. On each installation open License Manager and import that slip file.

MMX version 15.0.15 now supports Delphi 10.4 Sydney.

You should be aware that assigning to TPicture.Graphic will create an internal copy of the source (see TPicture.SetGraphic), so you get a memory leak with the above code. As TPicture.Assign also uses SetGraphic internally, the above ist still valid for that one. Not refreshing the display may have a different cause.

Right. You only need to contact the Embarcadero Server when you register your Network License with your ELC instance and when this license get updated while your are on Update Subscription. I am not sure if I understand you here. As I said above: you need to register your Network License once when you enter it into your ELC Server instance. You also need to update this License whenever a new Delphi version is released and your license is still under Update Subscription. Without any Update Subscription the Network License stays valid inside your ELC Server. What do you mean with renew license of older versions? I still don't get the meaning of this term. AFAIK, any valid Delphi license up to a recent version also covers all previous versions down to Delphi 2007. At least my own licenses do. I also don't get the IP address issue. The ELC server is not bound to any IP address. Only the server name must rename the same. That is similar to the normal Named Workstation license, which is also bound to the computer name. I haven't been in the need to try, but it should be possible to re-install the ELC Server with the given login credentials and certificate number (optional) as long as the server name matches the previous one. I can't help and I don't mean to insult, but your arguments feel like just trying to forcibly construct a broken system where nothing is broken in the first place.

That is not true! Installations are not limited. The restriction is that you can run multiple instances of the same IDE version (10.2 and 10.3 are different versions) on up to three different machines at the same time. That is you can run Delphi 10.3 on the same machine (as many as it can cope with) and still start Delphi 10..3 on two more VMs or physical machines, where each can run multiple instances. Together with that you can run Delphi 10.2 instances on up to three different machines, be it the a same as above or others. You just have to make sure that all these machines can connect to the ELC Server and you are logged in at these machines with the same user name the license is bound to (you can change that yourself in the ELC Server). My installations are spread over dozens of VMs and I never reached that 3-instance-limit.

Not sure how you do, but I have always just copy the Delphi 7 license data to another machine without any further registration. Actually I guess that Delphi 7 is not even covered by the ELC server - it is just way too old. At least you should still have the original CD, so no need to download. Also, I am not sure what the term renew their licences actually means in this context. Is this just registering a license or is it bumping the registration count? It is not even clear what Marco is saying to be taken away from former customers. He just says you lose access or download options. Well, he will have a hard timer to stop you to access your Delphi installation on your system. And again, move your Delphi installation into a VM and take care of backups. No need to install again, no need to register again and no need to bump your registration count. Perhaps you should tell your customers to do the same. BTW, I wonder how many software companies still provide installation files for like 20+ years old software - at no cost. (most of those companies probably don't even exist any more)
