Hi all tech savvy residents,

Its entirely possible that I'm being really slow but I don't seem to be able to install and use an additional copy of MOI even though I've now purchased an additional license so two people can simultaneously use the program here. We've been using MOI for a while and testing it out. We like it so much now that we've pretty much stopped using everything else. So I bought an additional license so that two people here can model at the same time. this machine in question initially had a copy of MOI installed but that was uninstalled and anew copy installed from the link in the confirmation email. but obviously there is a registry entry or something of the sort still on this system that prevents the program being recognised as having a separate license from the previous installation. I hope this is clear. how do I fix this please?

Many thanks in advance

Hi KRUM, yeah when you install MoI a second time if you have already previously entered in a license before it will find that previous license and use it automatically instead of asking you for a new one.

The previous license information is saved in 2 places where you will need to delete it from in order for MoI to prompt you to enter in the new license.

The first place is a text file inside of the "Application data" folder - to get to there go to the Start menu (or push Win+R to get the "Run" dialog box), and enter in %AppData% - that will then open up the application data folder which is in a slightly different location on different versions of Windows. Then inside there will be a folder named "Moi", and your moi.ini file (which holds your various program settings but not any license data you can leave this file alone) and a file named moi_v3_license.key will be there. The .key file is a little text file that holds the previously entered license key in it, delete that file to get rid of it.

Then there is a secondary place that it's also stored just in case there was some problem writing to AppData - that's in the registry so to remove that you need to run regedit and then go to HKEY_CURRENT_USER \ Software \ Moi and inside there will be an entry named moi_v3_license.key that also contains your license key, right-click on it and delete it and then you will have removed all previously entered license information and the next time MoI starts it will prompt you for it again.

Please let me know if you are still stuck.

Thanks, - Michael
