Appcrash Troubleshooting

Reader Question:
“Hi Wally, I am having problems with Appcrash and wondering how to fix it?“ - Jasmine A., Canada

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer:

Overview of Appcrash

Appcrash is a method of verifying data integrity. It is normally used on networks and storage devices like hard-drives and flash memory cards. Appcrash is often shortened to CRC. W. Wesley Peterson developed the CRC process in 1961.

The way CRC works is fairly simple but very effective. It uses a mathematical algorithm to detect errors during transmission. A value is calculated based on the data in a particular block. This value is attached to the block of data. When the data is received on the storage device or attempts to be used by a program, the value is again calculated for the block of data. If the new result does not match the value attached to the block of data, the data is determined to have become corrupt and an error message is displayed.

CRC is used in a variety of different technologies. In computers, it is used to ensure that data is copied correctly when an application stores data, a file is downloaded from the Internet or transferred from removable media, like a DVD, to the hard-drive.

What Problems are Associated with Appcrash?

Appcrash errors happen with a variety of different programs and can happen at any time. If a program consistently generates an Appcrash error whenever it is started; the most likely cause is a registry issue.

When an Appcrash error is created while using a program; the cause of the error can be much harder to identify. One common reason for an Appcrash is a program conflict. If the user has several programs running at the same time, there is a chance that two or more are trying to utilize the same resources and this can cause one of the programs to crash and generate an Appcrash error.

Another common reason is an unstable file in the crashing program. Not all files in an application are required to run the program all the time. When the damaged file is required, the program will crash.

A programmer who can interpret the additional technical information included in an Appcrash error report easily determines the cause. Sometimes a computer system will perform much more slowly than normal after an Appcrash.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing! :)
