Overview

If you encounter a “Catastrophic failure when reading history” error during data transmission or export, it typically points to a misconfiguration in your system environment variables—particularly those related to Retail Pro.

This guide will help you verify and correct the necessary system settings to resolve this issue.

Step-by-Step Troubleshooting

✅ 1. Check the PATH Environment Variable

Retail Pro needs to be included in the system's environment variables to function correctly.

Here’s what to check:

• Open your system’s Environment Variables settings

  • On Windows, search for “Environment Variables” in the Start Menu

• Locate the System variable named PATH

• Make sure the full path to Retail Pro is included early in the string

🧠 Example:
If Retail Pro is installed at: P:\Retail\RPro
Then the PATH variable should include:
P:\Retail\RPro

✅ 2. Check the RPROWS Variable

Retail Pro also requires a workstation number to be set via another system variable.

To verify:

• In the same Environment Variables window

• Look for a variable named: RPROWS

• Confirm it is set to the correct workstation number for this device

🔧 If you're unsure of the correct workstation number, check with your Retail Pro administrator or IT support team.
