Hi Muhammad
There are some permissions around what users can upload , launch and view SCORM packages
Can you check the user all the permission to upload launch and view the package .
From the error message it doesn't sound like this is the problem but sometimes the error messages don't accurately describe the problem.
If this doesn't help what authoring package are you using - there may be an issue with the package.
Are you or your partner able to create a support ticket so we can see what might be going wrong?
regards.
