I already know that, i hopefully didn't write anything, that lead people 
to the conclusion, that i want setup.exe to do that.

Sure, but that's still not what i'm talking about!

setup.exe currently does the follwoing to write a file:

1. open destination.file
successful: jump to 2
error: jump to 3
2. write content, close file and jump to 4
3. write content to another file, and tell windows to replace the 
destination-file on next reboot.
4. process next file

all i want setup.exe to do, is the following

1. same as step 1 above
2. same as step 2 above
3a. inform user, that file cannot be opened for writing because it is in 
use and ask the user, if setup.exe should retry
user chooses YES: goto step 1
user chooses NO: goto step 3b
3b. same as step 3 above
4. same as step 4 above

of course it would be nice to know which process is using the file, but 
that's not what i'm talking about! i'm just want setup.exe to avoid 
reboots by __interacting__ with the __user__!!!
