Android Question Compilation Error (Missing dll)

I have installed b4a in windows 7. When I compile myfirstprogram following error message appear.

aapt.exe: System error
the program can't start because api-ms-win-crt-private-l1-1-0.dll is missing from your computer.

Let me know how to solve this problem.
The path of aapt2.exe is C:\Android\build-tools\30.0.2 and the path of api-ms-win-crt-private-l1-1-0.dll is C:\Program Files\Java\jdk1.8.0_321\bin.
When I copy the dll file and paste to the C:\Android\build-tools\30.0.2 and compile the program again, following error message appear.

Best to upgrade Windows as B4A IDE will soon be 64 bit anyway.
Thank you very much for your advice.
In a similar problem in Android Question, I found a statement that using the version 27.0.1 for build tools can solve the problem.
I want to know that it is also possible to solve my problem. If so, I also want to know how to get the version 27.0.1 for build tools.
Thank you very much for your patient reply.

I don't know whether it will work. The latest version of B4A depends on features which were not available in old build tools.
The build tools are part of Android SDK. You will need to look for an old Android SDK. Overall it will be a waste of time.
Thank you very much.
