Hello,
I saw you posted the following key:
HKEY_CLASSES_ROOT\Software\Adobe\Acrobat\Exe
to change the default application.
I don't have that key and/or do not understand what to edit it to.
I have Adobe Pro as the default and want to change it to Adobe Reader 8.0.
I've tried the usual way in Windows Explorer (no, not IE) and could not get WindowsXP Pro SP-2 to make the change.
This problem prevents me from viewing .pdf documents in my browser (FF).
Please reply and give me more detail as to how I would make this change.
I am about to pull my hair out!
Thanks for your help.
Regards,
Steve
Don't pull your hair out - takes 7-years for the folicles to recover and grow anew! Then your S.O. will think you have mange or something like that.
The
HKEY_CLASSES_ROOT\Software\Adobe\Acrobat\Exe
Is the link that points to where the default exe is located for the application.
The first line of attack would be to remove Reader, reboot, then reinstall. It should pop up asking you what you would like for your default app. Choose Reader over Acrobat (default).
The critical thing to keep in mind that in a browser it's not the file extension that drives the app launch but the MIME type.
As I am not an FF user (not by choice, corporate policy) I cannot provide you with specific details, but within FF, under the settings/options/preferences area you should be able to find a list of all the various MIME types (you want 'application/pdf'). There you should be able to change the application pointer to the desired installation.
Second line ...
If you want to hack the registry, HKey_Classes_Root\.pdf is it's entry. Under there, dig out the HKey_Classes_Root\.pdf\ShellEx entry - you will find a long hex string in {}, grab the DATA element out of the (Default) entry for the aforementioned string. This is the desitination pointer you want to traverse.
Copy the string into your clipboard then do a search on it...
Mine traversed to a registry entry that caughed up:
"C:\Program Files\Adobe\Acrobat 8.0\Acrobat\pdfprevhndlrshim.exe"
Hurm... PDF Preview Handler Shim? Shoulds promising. Keep digging from there.
And yes, there are direct entries for the PDFPrevHndlrShim and PDFPreviewHandler, with CLSID's that point back to their respective entries.
Be careful - you can very easily turn your fine running workstation into a rather expensive brick through one errant keystroke. Registry changes are immediate with no 'undo'.
Personally, I would really try the remove Reader and reinstall avenue first. If that doesn't work, right click, save the PDF to the desktop (or some other temp local store) and open them from there. As you can see, this stuff can get rather tortous in its tracing out.
Sorry I couldn't give you a definitive answer, but hopefully some hope and ideas.
Thanks.
