I have Windows 7 64bit now.
When compiling scripts the compiler closes automatically after a second without showning any errors.
Correct scripts run properly as always.

EDIT: When you select open included scripts in SED the SED only opens the first included file in each script.

delete -eq from sed commandline. (in preferences)

I have Windows 7 64 Bit and I get the errors just like before.
Check what quadraxas said.

I also have Windows 7 64bit, no problems.

you have to click on the blue arrow. then it will show errors.

my A6 works also fine on Win7 64-Bit

Thanks Quadraxas!
It worked.

Whats with SED opening only the first included files in a script?
EDIT: It seems it is like that because i use paths.
