svnsync - svn pre-revprop-changes error -

i @ wits end. have problem 2days , answers came have no effect. searched on net possible solutions , did of those, still no effect. saw answers in linux , dont know commands use if i'm gonna in windows.

i want sync 2 repositories. followed procedures here here also.

here's error i'm getting:
svnsync: e165006: repository has not been enabled accept revision propchanges;

i edited pre-revprop-change hook , here's added:

if "%3" == "sync_user" (goto :label1) else (echo "only sync_user can make changes">&2)  exit1 :label1 exit 0 

i changed permission of 1 of repos still error.

pre-revprop-change hook must named (in case of windows) pre-revprop-change.bat in order enable os execute it.
