xnview MP cannot open .ico and .jfif

[mulanee]

Hello,
With xnview MP, I cannot "open with.." some files extensions.
As for now: .ico and .jfif
When I open xnview MP and file/open, it works.
I have not this issue with xnview classic

[xnview]

if you drag&drop .ico or .jfif on xnviewmp icon, it works?

[mulanee]

Yes it works.

I installed the latest version.
Still the same behaviour, double clic doesn't open the file, only opening xnviewmp

[xnview]

you need to check registry entries

you need to check registry entries

I did it but nothing to learn.
.ico is written to be opened with xnviewmp.

And in fact it is what is happening, except the content of the .ico is not shown:

if you try to drag&drop a .ico on XnView MP's icon, same thing?

[mulanee]

You asked already, İ said yes

Sorry i've tried with 0.97.0, and i can drag&drop correctly a .ico on XnView MP's icon

[mulanee]

I am able too
This is not the problem

[xnview]

if it works, it seems that you have a problem in the associated registry entry

Maybe but where?

Nota: even in admin mode, I am not able to change the files association, clicking on the button makes nothing

Hello,

Instead of portable version I installed the new release through the installer.
Seems far better then..
