I got that error trying to reinstall GMLib (GMLib_DXE5_FMX.bpl):
[dcc32 Fatal Error] F2039 Could not create output file 'C:\Users\Public\Documents\RAD Studio\12.0\Bpl\GMLib_DXE5.bpl'
[dcc32 Fatal Error] GMLib_DXE5_FMX.dpk(36): E2202 Required package 'GMLib_DXE5' not found
What can I do to solve this?
