[Wine] wine path error?

[rufus]

hello there 

i´ve got wine version 1.3.26 on my gentoo machine installed.
My problem is I cannot start any game/program by using the wine + path parameters. For example when i want to start gta sa:

my normal usage is: 
wine "c:\programme\rockstar games\gta san andreas\gta_sa.exe"

But nothing happens...

But if i change direct into gta´s directory, i can start gta with this usage:

wine gta_sa.exe 

and it runs perfect!

How could it be?

Sorry for my poor english...
