@TAZZ, @ ANDREASAYANG
From the picture you can see it is searching for a folder (which exist in BOTH F:\FPC and my lazarus install(s) F:\Lazarus\fpc\3.0.2\units\i386-win32\rtl\), the RTL folder.
That is ALL you see.
Both the RTL folder exists.
You are ALSO informed that these sources which the user installing the app, is told it is in the RTL folder. Again, these exists - doesn't matter which one I choose
You DO NOT see it stating it has to be under lazarus.
I have the same FPC installed in a different folder, which I prefer. I like my compilers SEPARATE from my IDE's. Nothing wrong with that. If lazarus app does not like that, it should be stated at the time of install.
So my question SHOULD have been, what specific file(s) does lazarus needs - in the existing RTL folder, that do not exist? And shouldn't Lazarus come with the missing files?
thanks
