Thanks to everyone who helped me. I managed to solve the problem.
After reading the comments, I realized the mistake I was making. The file has to be specifically .zip, but I thought that any compressed file he would be able to interpret, but not. This may be due to my server, but I'm not sure. Sorry for my stupidity. kjsksjksjk
Thank you all for your help ...
I was able to get the same message about not being able to find the install file so I compressed your module as a .zip and it installed fine.
It is likely that your hosting environment is not able to handle the .RAR format.
