The TWAIN Problem
The first thing that you want to do is determine the Photoshop Elements version that you have. That will determine the steps that you have to take. More often than not, Adobe Photoshop Elements crashes because there’s a problem with your printer. If you are dealing with version 6 of Photoshop Elements, then it probably has something to do with the TWAIN technology.
TWAIN technology was found on older software programs and printers, and it controlled different types of image-acquisition devices. In this version of Photoshop Elements, the TWAIN component loads as soon as you open the program. The TWAIN component tries to communicate with either your scanner or any other TWAIN device on your computer.
If it can’t communicate with this device, it crashes Photoshop Elements. The problem, of course, is that most modern devices don’t have the TWAIN technology anymore. So, you should try disabling this element by following the below steps:
1. When using a Windows 32-bit system, go to Navigate to C:\Program Files\Adobe\Photoshop Elements 6.0\Plug-Ins\Import-Export\. If using a 64-bit system, go to Navigate to C:\Program Files (x86)\Adobe\Photoshop Elements 6.0\Plug-Ins\Import-Export\.
2. Next, rename the Twain_32.8BA component to ~Twain_32.8BA.
This should take care of the problem, but you won’t be able to use Import feature in Photoshop Elements. You can also delete old scanner files, except the wiatwain.ds file, in the C:/WINDOWS/Twain_32 folder.
