Hi Michael.

- Understood

> Is there a specific reason why you have set up a moi.ini file and an appdata folder underneath the install folder in c:\Program Files ?
- I had all in v4 folder so it would be portable. I got that somewhere here in the forum as I wanted to use MoI on my other computer with same configuration. I would like to have same flexibility with v5. I believe it's not against license terms (it's used only by me, no other user).

> Can you also show the moi.ini location for v4 (in v4 also go to Options > General > "Edit .ini file" button)
- it's in my D:\MoIv4\appdata\moi.ini

> Having the moi.ini file located under c:\Program Files is also probably what causes it to be read only...
- I understand. Putting ini file in user appdata solved the issue.

However, I tried to copy some stuff around into appdata, but I cannot get my plugins/addons (whatever they are called - on the picture) to display in v5.
I have some useful stuff there along with object library that I use very often.
With v4, I had all in one folder, portable program which was super easy to backup with complete custom configuration and objects.
