[MiKTeX] Error: Error accessing Windows API Important: Denied. Error: Windows API Error 5: Access denied. Looks different on Win10-PRO 64-bit machine. The log file is available at so. Thanks a lot!

The MikTeX program includes a package guide (for installing the already mentioned formatting packages using MikTex) and a miktex update that allows users to download current packages and updates as soon as they become available on the MikTeX website.

When I wanted to get “Beamer” via compressed MiKTeX “Windows API Error 5: Access may be denied”. This means that the program does not have read and write permissions for some of the folders it wants to change. There are three (I’m starting to see solutions) for this: just run “package manager” as administrator, i.e. press the right mouse button (RMB) and “run as administrator”.
Many people today elevate or elevate their permissions outside of folders to really get around “permission denied”. Please avoid this as it will probably explain other issues later. First, let’s look at the main reasons why downloading is inappropriate for your incredible rights. I would still recommend a simple portable setup to the user without the hassle of dual regulators.
Why is there an API 87 error on MiKTeX?
The current version is 2.9. The root cause of API error eighty-seven is that open content is blocking the installation. It could be another application, or two instances involved in a MiKTeX application, or even a region locked from a previous running compilation.
