Edge Preview handler taking over and won't work

Post by jasongordon »

Hi
Using Everything 1.4.1, I am trying to use the preview panel to look at PDF files.

I had re-installed SumatraPDF so it would install it's preview handler and take over handling for PDF files. This worked right after I did it.

However, somehow overnight something changed and it will not display in Everything.... the preview window is just blank. The computer was not restarted overnight. Now in Explorer's preview panel, all the PDFs just say "This file cannot be previewed." Directory Opus is the only thing where the preview is working. Yesterday after installing SumatraPDF, that was the viewer that was used in Directory Opus but now DO has reverted to using the Edge viewer.

Any idea what happened? I cant reinstall SumatraPDF everyday.
I exlusively use Everything to chew threw a huge directory structure of PDF files and I need to be able to preview them.

Help please. And thanks

Preview host running as admin and breaking things?
-Preview handlers hate running as admin.

Please make sure Everything is installed correctly and running as a standard user:
  • In Everything, from the Tools menu, click Options.
  • Click the General tab on the left.
  • Check Store settings and data in %APPDATA%\Everything.
  • Uncheck Run as administrator.
  • Check Everything Service. (Please make sure this is tick-checked and not square-checked)
  • Click OK.
  • Exit Everything (from the File menu, click Exit).
  • Restart Everything.
Restart your PC if you make any changes above.
Does the issue persist?

Everything uses the system for previ[*]
ewing files, meaning that Explorer and Everything should show the same preview.
In your case they actually do: both do not show a PDF preview.
Something is going wrong on your system. Instead of (temporarily) fixing it, there is another option:
Installing Everything 1.5. Here one can overrule the default system PDF viewer.
It takes a little more effort, but should give you a stable PDF preview.

Let me/us know if interested.

I installed 1.5a and cannot figure out how to configure the pdf viewer of my choice.

Also the filters do not seem to be working anymore.

In order to get any results of my indexed google drive folder, i need to make sure the Everything filter is active under the Search menu. But when I switch to one of my filters, I get almost no results.
