Installer error "mirc.ini file could not be located" if %APPDATA%\mirc.ini is used

[silv3rr]

1. Using mirc_fish_10-setup-2017-02-25.exe to update
2. Enter your path to mirc.exe here: "C:\Program Files (x86)\mIRC"
3. After clicking Next I get a Setup popup: mirc.ini file could not be located

- mirc.exe + ssl/fish10 dll's and mrc are in: C:\Program Files (x86)\mIRC
- mirc.ini + blow.ini are in: C:\Users\silver\AppData\Roaming\mIRC
- afaik these paths are used for the default way mIRC is installed nowadays.
- no portable flag set
- fish10 works fine with manual install from .zip

Can you please check if a portable setting exists in your mirc.ini and if it does, which value it is set to?

[silv3rr]

As I stated in the initial comment: no portable setting at all. Also says so in the debug output.
Just to make sure I just checked again:

C:\Users\silver\AppData\Roaming\mIRC>findstr /I portable mirc.ini && echo match || echo no match
no match

This behaviour is actually ok - if no portable setting exists, "yes" is assumed for legacy reasons.
