RAD Studio10.4.2 IDE doesn’t load IW15.2.29 Evaluation

[Alexandre Machado]

I suggest you remove the commented line from the rsvars.bat file altogether (or move it to line 2 instead of line 1). The setup program just parses the file (doesn't execute it) looking for BDSCOMMONDIR value (so REM won't actually disable the parser).

After that, installation of IntraWeb must install all BPL files into

C:\Users\Public\Documents\Embarcadero\Studio\21.0

folder
