You will need:
1. a copy of Crossover
3. a copy of some dll w$ XP libs, you can get them here. extract them to a temp folder on your desktop.
note: you can use the trial versions of crossover and fairbot.
STEP 2. instal fairbot, through crossover. i.e.
open crossover -> Configure (on menu bar) -> install software ->
install unsupported software -> continue -> new bottle (name it Fairbot) -> create new bottle and continue ->
click install-> and locate fairbot.exe (that you got from 2.)
STEP 3. replace DLL
On crossover menu bar -> Configure -> manage bottles -> select Fairbot bottle -> advanced -> click "make this the default bottle" -> Open c: drive in Finder -> go to Windows/system32 folder -> drag and drop all files from the temp folder you created to the system32 folder. close folder.
STEP 4. override DLLs
On the manage bottles menu -> Control Panel -> launch winecfg ->
go to Libraries tab -> on the dropdown box type and add the following:
msxml3
shdocvwshlwapi
-> Apply -> OK -> close Wine configuration -> close Manage bottles
STEP 4. add dll to registry
On crossover menu bar -> Programs -> Run Command... ->
(make sure fairbot bottle is select) -> Open Shell (it will open a Terminal Console) ->
run the following commands (one line at the time):
wine regsvr32.exe msxml3.dll
wine regsvr32.exe msxml4.dll
wine regsvr32.exe shdocvw.dll
wine regsvr32.exe msxml4.dll
wine regsvr32.exe shdocvw.dll
Close all.
Now you are ready to run fairbot, via the programs tab on crossover, or just use spotlight to trigger fairbot.
put your betfair username and password and you are ready to roll.
Note. I have tried it and the only problem I could find with the software was on the graphs. When in ladder mode, after opening a graph, I could change the event only once, then I needed to close and open the graph again. i.e. if I open the graph for one horse, I could change the horse only one time.
Hope this would come in hand to some people.
