hello molly
you where right GlobalSkipIfNoLeaks is not known by lazarus-1.6.4-fpc-3.0.2-win64.exe.
Eh... that's weird
FPC 3.0.2 should be enough (i use that version as well).
So how do I get a installation that is up to date? Or is there one coming on official site soon?
The 1.8 release should become a final release pretty soon. But somehow everything related to this release seems to be a bit ... well ... out of the ordinary. So, please don't hold that against me in case it will take another year before reaching final release
You should be good to go with your initial installation of lazarus-1.6.4-fpc-3.0.2-win64.exe. I would recommend to verify this with someone else first as i'm unable to verify myself at the moment.
I apologize for recommending to upgrade. I more or less expected that you would mention your current version first, before actually performing an upgrade. In hindsight that seem to have caused more trouble than you bargained for
Are you able to remove your current installation and re-install lazarus-1.6.4-fpc-3.0.2-win64.exe ? If not then please feel free to mention the errors you are encountering, so that we're able to solve them for you.
