Here is what you should do:
- Open RAD Studio 10.3 and go to Tools -> Options
- Navigate to Language -> C++ -> Paths and Directories
- First select 32 bit platform. Check "System Include Path" and "Library Path" settings for the *classic compiler*. Remove any path to old IW versions from there (including 15.1.21)

- Now repeat the same process but select 64 bit platform.

- Close RAD Studio 10.3 IDE
- Manually delete the whole folder where you have 15.1.21 installed.
- Download and install IW 15.1.22, from here: http://downloads.atozed.com/intraweb/iw15.1.22.exe
- Open RAD Studio 10.3 IDE.
- Create a new C++ Application using the IntraWeb Application Wizard. Save it to any local folder and build it. It should build flawlessly.
BTW, I just followed these exact steps on my test machine with RAD Studio 10.3.3 installed (plus and old IW 15.x version) and it worked perfectly.
