Hey there @kef2012
Assuming you were installing via the BigFix.me Fixlet
https://bigfix.me/fixlet/details/20433
You would backup and delete the folder
C:\Program Files (x86)\BigFix Enterprise\BES Server\Applications\bigfixMeSync
backup and delete the config file
C:\Program Files (x86)\BigFix Enterprise\BES Server\\Application\Config\bigfixMeSync.xm
backup and delete the registry key
[HKEY_LOCAL_MACHINE\SOFTWARE\BigFix\Enterprise Server\Applications\bigfixMeSync]
then restart the BigFix plugin
net restart BESPluginService
