I've just downloaded the GeoMaps demo and try to build it using Delphi XE6 and fail with the following:
[dcc32 Fatal Error] iopreviews.pas(2268): F2039 Could not create output file 'C:\Program Files (x86)\ImageEn\DelphiXE6\iopreviews.dcu'
It looks like it's trying to write to the program files and Windows won't let it.
I can't see anything in the code with any filepath references, so maybe its one of the compiler settings is wrong and XE6 is new to me.
Bruce. |

| Transferred the code to a new project and now things are working fine! |
