I hope this is helpful:
* If customer run a trialware and would like to upgrade to the full software, do they need to uninstall it or just upload the permanent file/ or decode the permanent key?
- Trialware can be fully activated once the customer has purchased the required licenses. Just to confirm, so once the customer got their permanent license file/key, customer does not need to uninstall the trial version instead, upload/decode the required license and it will be upgraded to a full software. The customer would not need to uninstall the trialware so that they can fully activate it.
* Are temp license keys/ files available?
- Temporary license are being sent when one requested and fill up the form for a trialware in symantec.com. However, not all products are available for trialware so it is advisable to contact Sales at 1-800-745-6054 option 3
