Troubleshooting eRx

This article covers common troubleshooting scenarios to resolve errors with eRx.

Permissions issues with eRx configuration (test)

eRx releases new versions of the adapter that transmits scripts to eRx. As part of a Bp Premier server upgrade, the old eRx adapter is uninstalled and replaced with the new version. The eRx adapter files are stored in the folder C:\Program Files\eRx rather than in the folder C:\Program Files\Best Practice Software\BPS\eRx.

If a Bp Premier upgrade or eRx configuration fails due to permissions, access to this folder may be a cause. Practices with IT policies that restrict access to local and network folders will need to provide access to the folder C:\Program Files\eRx for the upgrade.

Prescription barcodes are not printing correctly

If barcodes on prescriptions are not printing correctly, you may be able to resolve the issue by downloading and running the Bp Fonts utility.

1. Navigate to the Bp Premier downloads page.
2. Find the Bp Fonts utility and click Download.

You may see a warning that BpPremier_Fonts_QH.exe may not be safe to download. You can safely download and keep the file.

3. Navigate to the folder that you downloaded BpPremier_Fonts_QH.exe to. Right click the file and select Run as administrator.

If the problem has not been resolved, contact Bp Premier support for further troubleshooting.
