PDF File Opens in Print Mode

Issue

When double-click to open a PDF file, it automatically brings up the Print dialog box in Right PDF Reader or Right PDF Pro (Gaaiho PDF Reader or Gaaiho PDF Suite).

Description

1. If this only happened to specific PDF files, these files are probably embedded with JavaScript.
2. If all PDF files are acting this way, it is likely that some information is missing in your "Registry". This happens in some specific operating systems with a slight possibility. 

Solution

Solution 1:

1. Open Right PDF Editor or Right PDF Reader (Gaaiho Doc or Gaaiho PDF Reader)
2. Go to "File" > "Preferences" > "JavaScript", and uncheck "Enable JavaScript"
3. Now try open the same file again

Solution 2:

Login to your "Registry Editor (regedit)" and follow below instructions:

1. Run or Search for "regedit" to enter "Registry Editor"
2. Go to the following path (if you are using different product, please substitute GaaihoReader.Document according to the product you have).

Right PDF Pro: RightPDFEditor.Document

Right PDF Reader: RightPDFReadeer.Document

Gaaiho PDF Suite: GaaihoDoc.Document

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Classes\GaaihoReader.Document\shell\open\command

1. Right click on (Default) and select "Modify..." and input C:\Program Files (x86)\Zeon\Gaaiho\Gaaiho Reader\bin\GaaihoReader.exe" "%1" into Value data field
   

Note: please make sure the path is identical to the actual installation path
