How to Install (anyone) - How I did in my install:
My RAD Studio 10.4.1 is in C:EMB <--- my root for Embarcadero softwares
----------
--- C:EMBRAD1041 <--- my RAD 10.4.1 root
--- C:EMBRAD1041in
--- C:EMBRAD1041...
1) Copy your "Hotfix - zip file" for one folder anyone
...> I unzip this file in my C:EMB folder - you can choice anyother place if you can!
2) open CMD as Admin, and go to folder where is the files unziped!
...> in my case: c:EMBCompilerLSPHotfixGeneral-20201104 <--- my files unzip
3) you'll see 3 files : "PatchTool.exe", "ReadMe.txt" and "delphi.compilers.hotfix.zip"
4) you'll use the "PatchTool.exe" to install or uninstall the patches in RAD Studio, like this!
5) type the command-line:
PatchTools -f delphi.compilers.hotfix.zip -b 21.0 -a
NOTE: using -u on command-line, you can "uninstall" this patch!
for all options type: PATCHTOOLS.EXE <--- without any params
6) wait the installation and it's ready!
7) if all it's ok, you'll have a new folder named: "C:<<RAD-STUDIO-FOLDER>>\_patch-backup" in your RAD Studio installation.
... see the "install.log" file to see what files was added or replaced!
