Solution for a Windows 32-bit Code42 app running on a 64-bit system

If your Windows version is 64-bit, you must ensure that your Code42 app is also a 64-bit version.

Step 1: Determine your configuration

Follow the steps below to determine both your operating system version and Code42 app version.

Determine if you have a 32- or 64-bit operating system

  1. Open the Windows Start menu.
  2. Select Settings > System > About.
  3. Note the System type. It indicates if you are running a 32-bit or 64-bit operating system.

Determine if you are running a 32-bit version of the Code42 app 

Follow the applicable set of steps below for your install type (default or per user).

Code42 app installed for all users (the default)

To determine whether your Code42 app is a 32-bit or 64-bit version:

  1. From the Windows Start menu, open File Explorer.
  2. Navigate to Local Disk (C:) in the left-hand column.
  3. Select Local Disk (C:).
  4. In the list at right, look for:
    • Code42 app version 8.2 and later: C:\Program Files\Code42
    • Code42 app version 8.0 and earlier: C:\Program Files\CrashPlan
  5. Do one of the following:
    • If you see C:\Program Files (x86)\Code42 or C:\Program Files (x86)\CrashPlan, you have a 32-bit Code42 app running on a 64-bit operating system. Proceed to Step 2.
    • If you see C:\Program Files\Code42  or C:\Program Files\CrashPlan, you have a 64-bit Code42 app running on a 64-bit system. Proceed to Solution for any 64-bit system

Note: If C:\Program Files\Code42  or C:\Program Files\CrashPlan does not exist, your Code42 app runs for a single user rather than all users of your machine. See Code42 app installed per user, below.

  7. Select Properties > Compatibility.
    • If the Compatibility mode is Windows XP, you have a 32-bit Code42 app running on a 64-bit operating system. Proceed to Step 2.
    • If the Compatibility mode is anything other than Windows XP, you have a 64-bit Code42 app running on a 64-bit system. See Solution for any 64-bit system
