After the user turns on the computer, when running some programs, an error prompt appears that it is not a valid win32 application, and the software cannot be opened and used normally. At this time, checking the following points can usually solve this problem.
1. The program installation package is incomplete or has been tampered with, which may cause this problem. Go to the official website to re-install the next installation package and try again.
2. If the error message that multiple softwares are not valid win32 applications appears, it is estimated that there is a virus in the computer. Please use 360 or Tencent Security Manager to completely check and kill the computer.
3. Open the registry and delete the following keys (if any):
HKEY_CLASSES_ROOT\.exe
HKEY_CLASSES_ROOT\exe_auto_file
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\EXE
Then restart the computer.
To open the Registry Editor, press the "R key + Windows key" at the same time, type "regedit" and press Enter.
