I don't know why my pdf files are now opening in IE, instead of the pdf reader format. How can I get them back to opening in the reader format?
As per the issue description, your pdf files are opening in Internet Explorer instead of Acrobat Reader, is that correct?
Could you please try following the steps mentioned in the link below (applies to Windows 7 as well)?
Keep us posted with the results.
Im glad that helped the person who asked this question initially, im having the same issue but I've pretty much tried everything including the suggestion above.
So far I have tried:
Checking file associations of PDF with Acrobat
Disabling all Extensions from browser (IE)
Within Adobe Acrobat and according to suggestions making sure that pdf files open only with Acrobat
Kinda stuck now.
Any suggestions as the adobe support just told me to come here as they couldnt help.
