>- I need the registry path for Acroread. If anybody has installed it, please send it to me.
I started working on this. My thoughts was to extract the pdf viewer associated with pdf's on the windows machine. With: ---------------------------------------- Function getFileAssociation Exch $R1 Push $R0 ReadRegStr $R0 HKCR "$R1" "" ReadRegStr $R1 HKCR "$R0\shell\open\command" "" Pop $R0 Exch $R1 FunctionEnd And then using: Push ".pdf" Call getFileAssociation pop $acrobat_path ------------------------------------------ The result is: "C:\Program Files\acrobat\acrord32.exe" "%1" So you'll still need to do some parsing, but this will cater for acrobat and other pdf viewers. So maybe in lyxrc.defaults add the line \viewer pdf "acrord32" ?? Regards, Johann
