The plastic creaked under Alex’s grip as the final cutscene of Assassin’s Creed: Valhalla began to play. Eighty hours of raiding, puzzle-solving, and story-reading had led to this moment. He watched the credits roll, satisfied, waiting for the familiar bloop-bloop sound of the completion achievement unlocking.
Instead, the screen flickered. The Ubisoft Connect overlay minimized itself, and a stark, white error message popped up over his desktop wallpaper:
"The procedure entry point uplayachearnachievement could not be located in the dynamic link library."
Alex stared. The sentence was a word salad of technical jargon. He clicked "OK," confused. He opened the Ubisoft Connect client. It showed he was online. He launched the game again. It worked fine. But when he checked his stats, the playtime was zero. The cloud sync icon was spinning endlessly. He had just lost his save file.
The Diagnosis
Most gamers would restart the PC. Alex did. It didn't help. The error persisted every time he tried to launch the game. He took a deep breath and looked at the error message again, treating it not as a crash, but as a puzzle.
"The procedure entry point uplayachearnachievement could not be located..."
This specific phrasing was the clue. "UplayAchieveAchievement" wasn't a random error code; it was the name of a function inside a specific file. The computer was trying to run a command (likely to trigger that achievement popup) but couldn't find the instruction manual.
The "Dynamic Link Library" (DLL) is that manual. It’s a file ending in .dll that contains code multiple programs can share. The error meant that the file existed, but it was the wrong version, or it was corrupted. It was like trying to find the recipe for a specific sandwich in a cookbook, only to realize someone had ripped the page out. uplayachearnachievement could not be located
The Hunt
Alex opened File Explorer and navigated to the game’s installation folder: C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher.
He was looking for the heart of the launcher: upc_r2_loader64.dll. If this file was damaged, the entire communication network between the game and the Ubisoft servers would fail.
He found the file. It was there. But the error implied it was "dirty."
The Solution
Alex knew that simply deleting the file would break everything. He needed a clean slate. He opened his web browser and navigated to the official Ubisoft support site. He ignored the general "restart your computer" advice and looked for the "manual uninstall" or "clean install" instructions.
He didn't just uninstall the game. He uninstalled Ubisoft Connect entirely.
Then, he did the crucial step most people skip. He opened the Run command (Windows Key + R) and typed %programdata%. He navigated to the Ubisoft folder and deleted the Ubisoft Game Launcher folder entirely. This cleared out the cache, the old DLLs, and the corrupted configuration files—the "dirty" parts that the uninstaller often leaves behind. The plastic creaked under Alex’s grip as the
He rebooted his PC.
The Reunion
Alex downloaded the latest installer for Ubisoft Connect from the website. It was a small file, only a few megabytes. He ran it. As the progress bar filled, he watched the File Explorer. A fresh, pristine upc_r2_loader64.dll was placed into the directory.
He launched Ubisoft Connect. He logged in. He launched Valhalla.
The game loaded. The overlay appeared instantly. He checked his save games. The cloud sync worked. He loaded his last save, walked his character forward, and triggered a small side objective.
Bloop-bloop.
Achievement Unlocked: The Hunter.
The Lesson
The error "uplayachearnachievement could not be located" is terrifying because it looks like a fatal system flaw. But Alex learned that 90% of PC gaming errors are simply communication breakdowns.
If you see an error about a missing "entry point" in a DLL:
ProgramData or AppData. This is where the corruption hides.The error wasn't a dead end; it was just a request for a clean install.
If you are launching via Steam or Epic, try launching the game directly from Ubisoft Connect. Sometimes the intermediary launcher causes pathing errors. Open Ubisoft Connect manually and launch the game from there (without Steam running).
For PC gamers, few things are as frustrating as a game that refuses to launch. You click "Play" in Steam or Ubisoft Connect, the loading icon spins for a moment, and then... nothing. Or worse, a cryptic error message flashes on the screen before vanishing.
One of the most persistent and confusing errors plaguing Ubisoft titles in recent years is the message: "The procedure entry point UplayAchievementEarnAchievement could not be located in the dynamic link library uplay_r1_loader64.dll."
This error is a mouthful, but it tells a specific story about a breakdown in communication between your game, your launcher, and your operating system. Here is a deep dive into what causes this error and how to fix it.

| Cause | Description | |-------|-------------| | Corrupted local cache | Ubisoft Connect stores achievement data locally; if corrupted, it fails to match server data | | Outdated client | Older versions may have mismatched achievement IDs | | Server sync delay | Achievements unlock server-side but client fails to locate them immediately | | Game update mismatch | After a game patch, achievement IDs can change | | Offline mode conflict | Achievements earned offline sometimes fail to sync properly |
Check for client updates manually.
