Flawlessly is questionable. There has been at least one report of Error Insight killing the IDE for a large project and no apparent ability to completely disable it.

There's a potential show-stopper for non-Windows platforms https://www.ideasawakened.com/post/rad-studio-10-4-2-is-great-but-here-are-some-notes

I assume everyone running VirtualBox with 10.4.2 will get this error with no workaround?

Did the changes solve your problem?

You should not do a seperate manual uninstall. If you manually uninstall, then you should manually save your settings first. If you use the installer to install 10.4.2 and let it uninstall the prior version then you will be prompted to save your settings.

Nope. It works fine for me on a clean install of 10.4.2 Perhaps you have some IDE Experts installed like CNPack or GExperts? If so, I'd try to remove them and try it again.

Note: If you install 10.4.2 with the offline ISO you still have to put GetIt into online mode which can be done from the command prompt after installing: GetItCmd.exe -c=useonline

You can join a Delphi related Telegram group for free, here are two: https://t.me/delphidevelopers https://t.me/DelphiProgramming_Eng Post a question on Telegram and see if you get a quick response. I know there are some Russian speaking developers on there. I would assume there's a Russian-only Delphi Telegroup available as well.

I'd give the graphics card more virtual memory, disable acceleration, and maybe a different controller choice. I hope something works!

Yes, I'd assume it's incompatibility on the virtual graphics hardware. Maybe check for updates on VirtualBox, or tweak the settings to a more generic display (if possible, it has been a while since I used Virtual Box)

I installed offline to a clean install of Windows 10/20H2 and I cannot reproduce. (Target system is running on VMWare Workstation though.)

That is supposed to be automatic. There's a new progress bar showing CodeInsight activity - is that doing anything?

With the occasional exception, binaries should be compatible across the major version releases. (10.4 and 10.4.1 and 10.4.2) https://www.ideasawakened.com/post/about-binary-compatibility-on-new-versions-of-delphi

Indeed! Just wrote a blog post on that: https://www.ideasawakened.com/post/rad-studio-10-4-2-is-now-available-with-a-much-enhanced-error-insight

Also note - it was stated in the 10.4.2 release webinar that the online help wasn't completely updated for 10.4.2. The online wiki was updated, but the help is not completely up to date with 10.4.2. One nice improvement with help is that you click on a compiler error and hit F1 to bring up the help for that error. (Used to work back that way in Delphi 7)

Marco's announcement on the new blogs site: https://blogs.embarcadero.com/rad-studio-10-4-1-has-been-released/ Updated my wiki page with info on 10.4.1: https://github.com/ideasawakened/DelphiKB/wiki/D27.SYDNEY.10.4.1.0 RAD Studio 10.4.1 has a strong focus on quality improvements. Key quality focus areas include: IDE Delphi Code Insight (LSP) Parallel Library SOAP & XML C++ Toolchain FireMonkey VCL Delphi Compiler iOS Deployment New Features Packages can now have an automatic version suffix (instead of manually updating and specifying the right version suffix with each new release) New reader-write lock implementation via the new TLightweightMREW record Faster and more lightweight than the TMultiReadExclusiveWriteSynchronizer (TMREW) Works across all platforms (TMEW was a simple critical section on some) Much improved support for multi-monitor desktop layouts and 4k monitors The floating form designer has been removed The Broadcast to devices option is now off by default Platform Support Deployment to Windows Server 2019 now supported The LSP based Code Insight much improved from its initial 10.4 release

Are you using a Profiler to measure performance of your application, or simply timing specific code snippets? I'd suggest a Profiler if you aren't using one now...you'll tyipcally see the big bottlenecks pretty easily.

You don't want to validate a name. You want to validate a logon session against your domain controllers. You could also split the secure features in the DLL into a different DLL and put that secure DLL into a place on the network that only authenticated users have access to. (That doesn't help if someone makes a copy of the DLL and exposes it later.) Finally, consider adding the secure DLL code to a web service and authenticate the calls made to the service,

Perhaps. I'm testing this particular machine out as I could swear that I disabled it in the registry already. I know for a fact that I changed the Windows Update service in SCM to be disabled and it was running after a reboot. Microsoft is definitely getting more aggressive at ensuring updates are still occuring. Another option that I enabled is to set the network connection to be metered. That plus the registry setting should effectively kill it. If not, there are some other tricks available.

LOL. Feed that dog an extra snack.
