Hi! I’ve been having this error when I use openPDC, I don’t know why… I already tried uninstalling it and installing it again, but it’s not working. Can someone help me with that, please? Thank you! ![image](http://discussions.gridprotectionalliance.org/uploads/default/original/2X/7/7be5a733c3a0191f757deb3c2bd430c45249d315.png) ---

Hi leticia\_acs, The installer is supposed to add the service account to the `Performance Log Users` and `Performance Monitor Users` groups, which should grant it the access it needs to read the performance counters. You might want to double-check whether the account is a member of those two groups. Thanks, Stephen
