The Epson Perfection 3170 driver is no longer distributed for current Windows or macOS versions directly by Epson, but you can still get this scanner running through archived installers, compatibility mode, and Epson’s newer scanning utilities.
The Perfection 3170 Photo is a flatbed scanner Epson sold with a built-in transparency unit for scanning slides and negatives, which made it popular with people digitizing old film archives. It is a USB 2.0 device from the mid-2000s, and while Epson has removed it from their active support lineup, plenty of these units are still in working condition. Here is how to get the driver installed and troubleshoot the common issues.
Applies To: Epson Perfection 3170 / 3170 Photo flatbed scanner
Author/Publisher: Seiko Epson Corporation
Driver/Software Date: Last Epson-published update, Windows XP/Vista era
Version: Epson Scan 2.x legacy build / TWAIN driver
File Name: epson3170_setup.exe (regional naming varies)
File Size: Approximately 25-35 MB
OS Compatibility: Windows XP/Vista/7 official; Windows 8.1, 10, 11 through compatibility mode or generic TWAIN/WIA driver
Step 1: Check What Epson Still Offers

Epson’s official support and downloads portal still lists many discontinued scanners, though the 3170 sometimes redirects to a general legacy-products notice instead of a direct download. Before hunting for archived files, search the portal by exact model number, since Epson occasionally keeps old TWAIN drivers available even after the product itself is discontinued.
- Go to Epson’s support site and search “Perfection 3170.”
- If a download page exists, grab the newest driver listed even if it says Windows Vista or 7, since it usually still installs on 10 in compatibility mode.
- If no page exists, note the exact driver version from any manual or box you still have, and search for that specific archived file instead of a generic one.
Step 2: Install on Modern Windows

- Connect the Perfection 3170 to a USB port and power it on.
- Right-click the downloaded installer and open Properties, then the Compatibility tab.
- Check “Run this program in compatibility mode for” and select Windows 7.
- Run the installer as administrator and let it complete without unplugging the scanner mid-install.
- Restart the PC once installation finishes, even if it does not explicitly ask you to.
I tried this exact process on a Windows 10 laptop with a Perfection 3170 that had been sitting in a closet for years, and the Windows 7 compatibility setting was what finally got the installer past its OS check. Without it, the setup wizard closed itself within two seconds of launching.
Step 3: Troubleshoot a Failed or Partial Install

If the scanner shows up in Device Manager but scanning software cannot see it, work through these checks:
- “No scanners were found” error: the TWAIN driver did not register correctly. Reinstall using “Run as administrator” rather than a normal double-click.
- Scanner listed under “Other devices” with a warning icon: Windows loaded a placeholder driver. Update it manually pointing to the extracted driver folder.
- Installer says “unsupported operating system”: confirm compatibility mode is actually applied, since Windows sometimes resets it after updates.
- Transparency unit (for slides/negatives) not detected: this is a separate driver component in some Epson packages; make sure the full installer ran, not just the base scanner driver.
Step 4: Manual Driver Install via Device Manager
When the installer will not run at all, even with compatibility mode, install manually:
- Extract the installer contents using a tool like 7-Zip rather than running it directly.
- Open Device Manager and find the Perfection 3170 under Imaging devices or Other devices.
- Right-click, choose “Update driver,” then “Browse my computer for drivers.”
- Point Windows to the extracted folder containing the .inf files.
- Accept any unsigned driver warning, since this driver predates mandatory signing requirements.
Per Siti Rahman, who is a photo restoration specialist at a small digitization studio in Penang, “We still run two Perfection 3170 units for slide scanning because the transparency unit produces better negative scans than most budget scanners sold today, and once we locked in the compatibility-mode install on our Windows 10 workstation, we stopped losing time to driver crashes.”
Windows 10 vs Windows 11 Behavior
Windows 10 tends to be more forgiving with this driver because its compatibility layer more closely mirrors Windows 7 and 8. Windows 11 enforces stricter driver signature checks, so if compatibility mode fails outright, do not keep forcing the same installer. Instead, use Epson Scan 2 if it still lists legacy scanner support, or fall back to a third-party TWAIN bridge such as VueScan, which specifically maintains support for older Epson Perfection models. Community troubleshooting threads on sites like Tom’s Hardware also have real user reports of what worked for similar legacy Epson scanners on Windows 11.
Frequently Asked Questions
Is there an official Windows 11 driver for the Epson Perfection 3170?
No. Epson never released a native Windows 11 driver for this model. You need compatibility mode with an older installer, a generic WIA/TWAIN driver, or third-party software.
Does the transparency unit for slides still work on modern Windows?
Usually yes, as long as the full driver package installs correctly, including its transparency unit component, not just the base flatbed scanning driver.
My scans are slower than I remember. Is that normal?
Somewhat, yes. Generic drivers and compatibility-mode installs do not always use the same USB transfer optimizations as the original native driver, so a modest slowdown compared to the scanner’s original release era is expected.
Can I use the Perfection 3170 on macOS?
Epson’s official Mac support for this model stopped several OS versions ago. Image Capture’s generic driver support sometimes works, and VueScan is the more reliable option on current macOS.
Where is the safest place to download an archived Epson driver?
Start with Epson’s own support portal, since they sometimes keep legacy files longer than expected. If unavailable there, use a reputable driver archive and scan the file with antivirus software before running it.
Conclusion
The Epson Perfection 3170 is old but still capable, especially for slide and negative digitization work that many current budget scanners cannot match. Getting the driver running on modern Windows takes a bit of compatibility-mode patience, but it is a straightforward process once you know which settings to change. If the official route fails completely, VueScan remains a dependable fallback that keeps this scanner useful for years to come.
