Thank you, getobject is a roundabout, but solves the issue. BTW I discovered that

 system("taskkill /f /im Excel.exe") # kills the process just fine.

The second problem is not due to the backslash vs slash, you can try and see that using the forward slash works fine from ESS. The q. is how to submit a second argument to "Close"?
Submitting a second argument to Open works fine as shown by the "0" below, but neither "1" nor "-1" worked for Close. Very strange.

I know it won't answer your question exactly, but using comGetObject instead of comCreateObject won't create new Excel instances, so at least you won't have more than one processes running, so this might solve some of your problems.

As for your second problem, I would venture to guess you need your paths with double backslashes instead of slashes. The following just worked over here:

  wb<-comInvoke(comGetProperty(obj,"Workbooks"),"Open", "C:\ \Documents and Settings\\Haris\\Desktop\\test1.xlsx")
