After installing pure data on windows 10 I made a mistake with the path flag under preferences -> startup.

Now I cannot get into the startup flag anymore. I only get this error:

WARNING: Font family 'DejaVu Sans Mono' not found, using default (courier)
pd: can't open
-nogui: can't open
-nosync: can't open
-path: can't open
"
C:/to/my/file.pd": can't open
(Tcl) UNHANDLED ERROR: extra characters after close-quote
    while executing

"
    ("uplevel" body line 3)
    invoked from within
"uplevel #0 $docmds"

Every time I completely remove pd and reinstall this keeps turning back.

Where can I really, REALLY remove pure data or at least these options?

Cheers, Wilf
