Hi guys,

a few days ago i was struggling with a bug which makes mouse down blow preview impossible for pdfs stored in OneDrive, if you use PDF X-Change Viewer.

Now i found that mouse down blow preview works fine also in onedrive if you use adobe acrobat reader.

I know there is a way to set up different programs to open pdfs in windows and preview in xyplorer.

My question is just, where do i find this "guid" for adobe acrobat? so that i could preview my pdfs with adobe, but i still want to open them with pdf x-change or with sumatra pdf.

thanks for your help

The current default one via text get("previewhandler", "pdf");

All others
00. Get ShellExView from http://www.nirsoft.net/utils/shexview.html
01. Start the 64-bit version of it, if your OS is 64-bit
02. Menu Options - [x] Show 32-bit Shell Extensions
03. Sort for column "Type", only "Preview Handler" is relevant here
04. Get the belonging CLSID for an application from the column "CLSID"
