026 - pdf preview

After some difficulties to be allowed to put the .dll file in the Scrivener directory, I got this to work properly… Yesterday…

Today, I can no longer view the .pdf files I import into my projects.

So I renamed the older .dll and closed Scrivener to relaunch it.
There I noticed that I was not prompted to “try”…
Still no way to view my .pdf…

Close again, open another project…
Now the prompt is there… but still no .pdf preview…

So I moved the old .dll to another location and launched again…
Still no preview…

Yesterday this worked fine…

Did I do something wrong ?
