After a long time and various versions of the test, it is completely usable, except for 64 people who have not tested it. The installation is simple and one step is enough. I personally test it with installation instructions, hoping to bring convenience to the majority of PSD software users. Some friends still don't know what this patch does. I would like to add that PSD software started from CS version before. After installation, files in PSD format in the computer can't display thumbnails. If you want to see the original picture, you have to open the software to know the content of the picture. After installing this patch, you can see the content of PSD format pictures in the folder without opening the software, which is quite convenient. Also note: copy the "psicon.dll" file to the system system32 directory, or you won't see the thumbnails after restarting. Step 1: extract to any folder; Step 2: copy psicon.dll to the system system32 directory; Psd, cdr and eps are three image formats, which are familiar to friends who do image processing. You can't view their thumbnails directly in the window. Only after installing the corresponding software can you view their thumbnails. After installing this patch, you can directly display the thumbnails in psd format in the system.
