Hi. We purchased a second instance of MOI.
We got 2 active installations of MOI on 2 different PCs.
In the past we used either the first or the second PC.
So on both is the same Serial.

But how could i enter the new, the second, Serial?

Hi B-W-Design, the license information is stored in 2 places, you'll need to wipe it out from both locations and then MoI will ask you for your license key again the next time you run it.

One is a file in the MoI appdata folder. To see where this is located go to Options > General and press the "Edit .ini file" button. A dialog will pop up that shows the location of the moi.ini file and the license key files will be in that same location. They are files named moi_v2_license.key, moi_v3_license.key, etc... Delete those license key files.

Then on Windows it's additionally stored in the system registry. You can remove that one by running regedit.exe and going to HKEY_CURRENT_USER \ Software \ Moi - inside there will be an entry named moi_v3_license.key which holds the same information as the file in AppData. Right click on it and delete it and then with both the AppData file and the reg key removed that should do it.
