For the three messages you mention, the list of Excel errors on Sharepoint state the following reasons for case <b>3. Error Code: &nbsp;FileOpenSecuritySettings </b><br />
<b>Message</b>: &nbsp;The file you selected could not be found. Check the spelling of the file name and verify that the location is correct. The file you selected cannot be opened at this time due to security settings for Excel Services.<br />
<b>Explanation</b>: &nbsp;A call to the OpenWorkbook method failed because of the administrator's security settings. This could happen for various reasons. For example, the file is too big; that is, its size exceeded the limit set by the administrator.<br />

However, given that sharepoint items in your workspaces may sometimes indicate a problem, such as an edit conflict or synchronization error, you may sometimes see synchronization error indicators appended to lists in a SharePoint workspace, or on SharePoint workspaces listed in the Launchbar. These errors are typically related to user authentication.<br />
All types of errors are explained here<br />

<br />
However, ensure that you have<br />
1) Checked in the item properly<br />
2) Have provided users with appropriate access<br />
3) the problem does not relate to the file itself or its sharepoint folder<br />
Try to:<br />
1. To check if the issue is related to the <b>excel file itself</b>. Backup the two files and upload the copies and see how it works.<br />
2. To exclude <b>the folder issue</b>, upload the excel files in problem to other folder which does not occur this issue and check the result.

Check the file to make sure there are no references to locations that do not exist or can't be reached. The messages you are receiving often indicate this problem.<br />

Hope that helps...
