DAI (GOTY) DLC Trespasser AND JOH not showing up anywhere

@Sydn3yLuna 

Please clear your temp files:

• Press the Windows key and "R" at the same time
• Into the new window, type or copy & paste:  "%temp%"   (Without the quotes.) > hit "ENTER"
• Now your Windows Explorer should have brought you to the "C:\Users\>your user name<\AppData\Local\Temp" folder. > Delete all files and folders in it.
  (If some files or folders can't be deleted, reboot and try again.)

Then:

• Go here and download "Revo Uninstaller". (The freeware version, Portable version works too.)
• Run "Revo Uninstaller" > Uninstall DAI.
• At the end of the main uninstall, Revo will ask you which cleaning method you want to use. > Select "Moderate" > Browse
• If "Remaining registration content found" is displayed > Select All > Delete > Next
• When "Remaining Data and Folders" is displayed > Select All > Delete
• Run "Revo Uninstaller" > Uninstall EA Desktop.
• At the end of the main uninstall, Revo will ask you which cleaning method you want to use. > Select "Moderate" > Browse.
• If "Remaining registration content found" is displayed > Select All > Delete > Next
• When "Remaining Data and Folders" is displayed > Select All (Make sure the "Origin Games" folder is not in the list) > Delete.
• Restart the PC > Reinstall the newest version of EA app from here.
• Reinstall DAi. > Test.

First of all, thank you for answering and for your attention.

I am grateful

I followed your steps, and now I can't access my save

(It says the save was on a more recent version of the game)

Does that means the DLC would be playable on another character, so a different save entirely ?
Or am I missing something ?

@Sydn3yLuna 

Do you use mods?

• Go into your Dragon age "Patch" folder: (By default)
  C:\Program Files\EA Games\Dragon Age Inquisition\Update\Patch\
• Open the "package.mft" file with a text editor.
• Change the "Version" number to one higher as it is. 
  (So if it is 13, change it to 14)
• Save the "package.mft"
• Test.

@Sydn3yLuna 

The patch number issue and the DLC issue are not related.
The patch number is a mod related thing, it doesn't interfere with the DLCs.

Please preform a clean boot and test the Game in clean boot mode.

Make sure your virus scanner and other security software and alos Afterburner and similar software is disabled.

If that still don't works:

Create a new Windows user account  (Administrator) don't use local special characters, use only  Characters from the ASCII table

• Reboot > Log in to the new user account.
• Test.
