Symptoms

What the error says

Android

“File format is not supported,” “Can’t open file,” or APK opens in a text editor instead of the installer.

Windows

“This app can’t run on your PC,” “The file is corrupt,” or Windows attempts to unzip the APK.

iOS

“Profile install failed” or iOS downloads a ZIP instead of the configuration profile.

Checklist

Quick fixes before re-downloading

1

Confirm the extension

On Android/Windows, open Files/Explorer → enable “show file extensions” → ensure it ends with .apk or .exe.

2

Delete partial downloads

Remove the corrupted file so the browser doesn’t resume it. Clear browser cache/download history.

3

Re-download via official link

Use /link/ or the nearest mirror. Avoid renaming or opening until the download finishes.

4

Verify the hash

Compare the SHA-256 with the file comparison table. Install only if it matches.

Common causes

Why “file not supported” appears

Cause → Fix map
Cause Symptom Fix
APK renamed to ZIP Android asks to open with Drive/Docs Rename extension back to .apk; open via Files → Install
Incomplete download File size is smaller than listed Delete file, re-download using direct link/mirror
Opened on wrong platform Windows tries to open APK or Android tries to open EXE Use the correct platform or emulator, or download the right installer
Antivirus quarantine File disappears or becomes 0 bytes Allow/restore from antivirus quarantine, then verify hash

Android-specific fixes

Handle APKs correctly

Rename file

  1. Open Files by Google → long-press the APK.
  2. Tap Rename → ensure it ends with .apk.
  3. Install via Files → tap the file → Install.

Use APK installer app

Install an APK installer (APKMirror Installer, Split APKs Installer) if your device struggles with split APKs or bundles.

Windows-specific fixes

When EXE says “not supported”

Unblock the file

  1. Right-click → Properties → General.
  2. Tick “Unblock,” Apply, OK.
  3. Run as administrator.

Use legacy build

Older PCs should use the Windows 7 client from the legacy guide.

Troubleshooting

If the error persists

Still not opening?

  • Download on another network or device, then transfer via SD/USB.
  • Check storage (need ~500 MB free for APKs, more for EXEs).
  • Follow the other error guides if “stuck at 0%” or “browser blocked” occurs.

Automation tip

Use a script to delete files that don’t match the expected hash:

if [ "$HASH" != "$EXPECTED" ]; then
  rm 1xbet.apk
  echo "Corrupted file removed"
fi

FAQ

File not supported questions

No. APK must remain an APK. If you need PC access, use the Windows client or install the APK in an emulator.

Messaging apps often compress/rename attachments. Download directly from the website instead of forwarding via apps.

Only if the file originally was an APK but your browser renamed it. Never rename random archives to .apk.
