When we change "service log on" option of MangoAutomation, GUID automatically has changed.
We changed "Log on as" option of MangoAutomation service. At first, "Log on as" option was Local System account, we changed with another account. Then, restarted Mango and Mango GUID has changed.
Is that normal that changing GUID automatically when we change service log on option?
Yes, the user chosen to run the application affects the mango GUID. If you need to amend who to run the system as, you will need to get in touch with the mango guys about changing your license to match your new guid.
