XnView Software

I just did the test, and personally, no problem :
- neither upgrading from 1.9.3 to 1.9.5
- nor installing 1.9.5 on a Pc that never "seen" before XnviewMP

I did my tests both on W10 and W11

So I guess it's necessary you are more detailed describing your issue if you want that Pierre may have a valuable action....

Okay, I'll describe the problem again:

When I select one or more archives (RAR or ZIP, it doesn't matter) and right-click, Windows Explorer crashes.
Occasionally, when I select only one archive, it works, but the context menu appears with a delay.
If I select multiple archives at the same time, Explorer always crashes.

This behavior does not occur if the XNView shell extension is NOT installed.

My system: XNView MP 1.9.5 x64, Windows 11 Pro x64 23H2, latest updates, 64GB RAM; AMD Ryzen 9

you 'll have the problem with 1.9.4 too?

I also had this problem with version 1.9.3 (I skipped 1.9.4).
It started suddenly, but I didn't see any connection between the installation of 1.9.3 and the Explorer crashing. The event log in Windows 11 said that it was a .dll from Kaspersky Premium that was causing problems. In the Kaspersky forum, I then came across a thread that blamed XNView for this. You know the rest.

EDIT:
Installed v 1.9.2 with Shell Extension, marked 14 RAR files and right klick: Everything works as expected, no Explorer crashes
