32 bit and 64 bit system files in Windows

The windows operating system stores both 32 bit and 64 bit system files under seperate folders.  Because 64 bit OS needs to be able to run 32 bit programs without confusing them with new paths, some paths are redirected to different folders depending on whether a 32 bit or 64 bit application looks at them. The same applies to some registry keys.  Basically, if you open explorer (which is a 64 bit program), you will see these folders: C:\Windows\System32 << your 64 bit system folder C:\Windows\SysWOW64 << your 32 bit system folder (Yes, the numbers appear to be exactly the other way round, looks like someone at Microsoft was trying to be funny!) However: When a 32 bit program, such as Atom, looks at your Windows folder, it will see these folders instead: C:\Windows\System32 << your 32 bit system folder ( !!! ) C:\Windows\Sysnative << your 64 bit system folder This ensures that under the path C:\Windows\System32 , all applicatio

To solve this issue, I had to remove the ".pycharm_helpers " folder from the remove device and then restart PyCharm so that the folder is re-created and files are copied again. Here are the steps with comma
