Solution 2. Upgrade Windows 10 from 32 bit to 64 bit

Specifically, you are attempting to start an application which is designed to run on the 64-bit operating system. But your computer is running 32-bit Windows. The 32-bit application cannot load a 64-bit DLL, thus the mixing up 32 bit with 64-bit environment brings about problem. Therefore, a good choice is to upgrade Windows 10 from 32 bit to 64 bit.

Before you upgrade to 64-bit, you must back up all of your important files with a free backup program. EaseUS Todo Backup allows all Windows users to back up their data under Windows 10/8/7 etc with simple clicks. It's free to back up anything you need. 

Step 1: Launch EaseUS Todo Backup software and then choose "File Backup", "Disk/partition Backup" or "System Backup" for different backup purpose.

Step 2: Choose the system, disk partition, files or apps that you want to back up. Then select a destination where you want to store the backup file.

Step 3: Click "Proceed" to start the data backup process.

Solution 3. Change the Value of the LoadAppinit_dlls Key

Since the problem is caused by unsigned or corrupted DLL, we can use Reget.exe to solve this problem. We can change the value of the LoadAppinit_dlls key to 0. LoadAppInit_dll basically is a mechanism that starts the DLLs in its reg-key when the program starts. So changing its value to 0 might solve the problem.

1. Hold Windows key and press R.

2. Type regedit.exe and press Enter

type regedit.exe and open it

3. Go to this path HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows.

4. Double click "LoadAppInit_Dll". Change its value data to 0 and click "OK".

5. Restart your computer

Solution 4. Check the Disk to Fix the Error

Hard drive issue is likely to give rise to various problems and checking hard drive can remove these problems. You can follow steps given below to check your hard disk for errors.

1. Click the Start menu and type cmd. Right-click Command Prompt in the result and select Run as administrator.

2. Type chkdsk c: /f /r in Command Prompt and press Enter key. This means you are going to check and repair the C drive. If you want to check another drive, replace c with the corresponding letter of that drive.

3. If your Windows is installed in drive C, then you'll get the message "Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)" Type Y and press Enter key.

4. After that check and see if the problem is solved.

If you don't have any technical know-how and want to minimize data risks, using third-party software could be a better choice. The Command line is suitable for computer professionals since wrong commands can cause severe problems. Therefore, we strongly recommend you try an automatic command line alternative.

What is the difference between Clone and Backup? In what cases should I use Clone?

Clone will copy one disk to another or one partition to another (unallocated space is also supported). Usually, this option is used to upgrade the current disk by creating an identical copy. Backup will generate a .PBD image file containing the selected files or system that can be restored from the .PBD image if needed.

What is the difference between System Backup and Disk Backup?

System Backup will auto-select the system boot related partition(s) as the backup source to make sure the system image can be restored properly.

As a computer newbie, what features should I use to protect my computer?

You can use System Backup to back up the system and boot partitions, use Disk/Partition backup to back up the data partition and add plans to run an automatic backup. If you use the computer frequently or have software that may cause boot failure of the computer, we would suggest you back up the computer every 1 to 2 days. For other situations, you can backup the computer once a week. In addition, you can schedule File Backup to back up the files which are changed frequently.

What kind of storage service should I use to save my backup images?

EaseUS Todo Backup can save backup images to internal disks, external disks, network drives, or free cloud(Google Drive, Dropbox, and OneDrive) and CD/DVD. It is suggested to save the images to the internal/external/network drives to save time as those kinds of disks have a better read-write speed. It is suggested NOT to save the image on the source disk, because once the disk is damaged, all the files on the disk will become unavailable and you will be unable to restore the image.

As a company network administrator, what features should I use to protect our internal computers?

It is recommended that you use the SQL Backup feature to back up your company's SQL server and Exchange Backup feature to back up the Exchange server. In addition, you can execute System Backup to back up the system and boot partitions on every computer and set a plan to execute the backup once a day or twice a week to ensure that the computer can be restored timely when it has boot issues.
