I have created a protocol handler to open acrobat reader dc . So as soon as a link in my webapp is clicked I am trying to launch acrobat with the local pdf file .
mypdf:c:testform.pdf this is the url I hit
This is the command in the protocol handler given :
"acrobat.exe" /A "zoom=1000" "%1"
But is says the "there was an error opening document the file name or volume label syntax is incorrect.
when replacing %1 with c:testform.pdf in registry acrobat reader opens the file with no problems.
