CrashPlan app restore not starting, "There was a problem. Try again"

Problem

Downloading files in the CrashPlan app's Restore Files menu is unable to start a restore. The Restore Files Options menu shows an error message when pressing Go to start your download: "There was a problem. Try again"

Environment

• Windows 11, version 10.0.26200. 
• CrashPlan app installed as system 

Resolution

To fix the app error, follow the steps below to ensure the folder is writable by administrators on your device:

1. Go to the folder C:\ProgramData\CrashPlan\conf\tmp\ on your system and delete it
2. Click the Windows button and search services.msc to open Windows Services application.
3. Locate the CrashPlan Service entry.
4. Right-click the CrashPlan Service and select Restart.
5. Reopen the CrashPlan app to verify the service restarted successfully.
6. Click Restore Files to retry downloading the files.
   CrashPlan may start a synchronization scan after it's opened, and you'll need to wait for it to finish before starting the restore.
7. If you're still seeing that error, use the Web Restore UI to download your files from the CrashPlan console.
