Step 1: Check System Type

The app may be 64-bit, but your OS is 32-bit (or vice versa).

• Press Windows + I → go to System > About.

• Look under System type:
  e.g., 64-bit operating system, x64-based processor

If your system is 32-bit, you can’t run 64-bit apps.

Step 2: Check App Version

Right-click the installer or app → Properties > Details.
Check the file version and architecture (x86 = 32-bit, x64 = 64-bit).

If it’s incompatible, download the correct version from the developer’s site.

 Step 3: Unblock the File

Right-click the file → Properties → at bottom, check Unblock if available → Apply.

Sometimes Windows blocks files from unknown sources.

Step 4: Try Compatibility Mode

Right-click → Properties > Compatibility tab
Check Run this program in compatibility mode for and select an older version (e.g., Windows 8).

Step 5: Re-download or Reinstall

Corrupt downloads can cause this. Always download from trusted sources. Re-download and try again.

Bonus Tips

• Avoid running random .exe files from the web. Use VirusTotal to scan them.

• If you’re on Windows 10 S Mode, it only runs Microsoft Store apps.
