Why does Styku crash after a scan when moved to a new computer?

Why does Styku crash after a scan when moved to a new computer?

If Styku crashes right after a scan — before the results appear — the most common cause is that the replacement computer doesn't meet Styku's minimum hardware requirements. Processing a 3D body scan is demanding work, and an underpowered CPU will hit 100% usage and force the app to close. The fix is to move the software to a capable machine and reactivate your license.

Step 1: Confirm the new computer meets minimum requirements

Before reinstalling or transferring anything, check that the replacement computer meets all of the following:

  • CPU: Intel Core i5 or equivalent (or better)
  • RAM: 8 GB or more
  • Storage: 256 GB SSD (not a spinning hard drive)
  • Display: Touch screen
  • Operating system: Windows 11

If the computer falls short on any of these — especially the CPU — that is most likely the cause of the crash.

Step 2: Check CPU usage during a scan

If you're unsure whether the CPU is the problem, you can confirm it while running a scan:

  1. Open Task Manager (press Ctrl + Shift + Esc).
  2. Click the Performance tab.
  3. Select CPU from the left panel.
  4. Start a scan in Styku Studio and watch the CPU usage graph.

If CPU usage climbs to 100% and stays there until the app crashes, the machine is underpowered and needs to be replaced.

Step 3: Move to a capable computer

Once you have a computer that meets the minimum requirements:

  1. Do not attempt to reactivate the license on the underpowered machine again.
  2. Install Styku Studio on the new, capable computer.
  3. Contact Styku Support to have your license key reset so it can be activated on the new machine (a license key can only be active on one computer at a time).

Step 4: Reactivate your license

After Support resets your license key:

  1. Launch Styku Studio on the new computer.
  2. Sign in with your account credentials when prompted.
  3. Enter your license key when prompted to complete activation.

Your license key is also available in the Styku Business Portal if you need to reference it.

Step 5: Reset the profiles list if customer profiles are not loading

After moving to a new computer, the local profile cache may need to be rebuilt. If customer profiles are missing or the list appears blank, reset the cache as follows:

  1. Close the Styku software and open the folder icon.
  2. Type c:\programdata\stykuV5\archive cache in the search bar.
  3. Locate the file named body_cache_v2.cfg and delete it.
  4. Reopen the software.

The software will rebuild the profiles list on next launch.

Important notes

  • Styku requires an active internet connection to validate your license and process scans. Make sure the new computer is online before activating.
  • A license key can only be active on one machine at a time. Support must reset the key before you can activate it on a different computer.
  • If you are replacing the original Styku-provided laptop, contact Support — they can advise on compatible hardware.

If this resolves your issue, no further action is needed.

If the problem persists, contact support and include: the make and model of the replacement computer, its CPU model and RAM amount (found in Windows Settings > System > About), a screenshot of Task Manager showing CPU usage during a scan, and the exact error message or prompt that appears before the app closes.

Applies to: Styku Studio V5, all Styku scanner models, Windows 11
