The issue is caused by the default settings in the product and Internet Information Services (IIS).
By default, the IIS website where the product is hosted has a file upload limit of only 30 MB. On the other hand, OfficeScan has a maximum upload size of 5 MB.
To resolve the issue:
- Open the IIS Manager.
- Expand Sites and select MDM Web Site.
- On the main window of IIS, double-click Request Filtering.
- On the Actions Pane, click Edit Feature Settings.
- On the Edit Feature Settings page, go to Request Limits > Maximum allowed content length (Bytes) and change the value from 30000000 to a higher value. For example, 524288000 = 500 MB.
- Restart the IIS Admin service and World Wide Web Publishing service.
- Log in to the TMMS console and upload your application again.
- Open the IIS Manager.
- Expand Sites and select OfficeScan.
