WinDbg skip all messages while debug dumps

Question

I made powershell script that debug .dmp files with WinDbg. Here is part when windbg runs:

$arguments = '-y srv*c:\symbols*https://msdl.microsoft.com/download/symbols -z ' + $dmpfile + ' -c ".ecxr; kc; q" -logo ' + $logfile
            Start-Process -wait $windbg $arguments

But sometimes I face messages like: "the command line arguments cannot specify more than one kind of debugging to start" and my script stops, unable to handle that. I need to skip message and go on next dump file. How can I run WinDbg to debug minidump files and skip these messages?

Try escaping $dmpfile with double quotes. ...bols -z "' + $dmpfile + '" -c ".e... — kerem, Jan 25 '16 at 08:41
You have an unpaired double quote in your string `$arguments`. I count 3. I suggest looking at what `$arguments` looks like to see how that is causing the issue. — Matt, Jan 25 '16 at 12:43
@Matt edited, actually i have '-y "srv*c:\symbols*https://msdl.microsoft.com/download/symbols;srv*"another_address" -z ' but before posting here I deleted second symbol path, and left first quote. — Alexey O, Jan 25 '16 at 13:47

put all your arguments in a txt file and pass it as a script file to -c so that you don't have to struggle with quote matching
