Talk:Windows Error code 2503 und 2502
> Before installing/uninstalling, you must then enable the "User" permissions
This is definitely a *BAD* suggestion - to add "all" permissions for user for system temp path. There are *correct* permissions for the Windows\TEMP folder. They are (on Win10:) full access for Administrators and System for this folder, its subfolders and files; full access for CREATOR OWNER for subfolders and files only; and special permissions for Users for this folder and its subfolders: folder traverse/file execution, create files/write data, create folders/append data. Advising to make anything extra is introducing security vulnerabilities; the more so not mentioning that it MUST be a temporary solution (but I still am sure it's wrong, and the problem lies somewhere else).
