How does OFC PDF-viewer detect Adobe?

[Jemimus]

Hello!

Just a quick question: How does the OFC detect which Adobe Acrobat installation to start in the viewer?
We currently install Adobe Actobat 7 Standard on our workstations, but we want OFC PDF-Viewer to use Adobe Acrobat Reader 9.1 to view the PDF's.

We manage to create this effect by, from a clean pc, install Acrobat 7 Standard first, then install Reader 9.
But I was trying to find how the PDF viewer finds the Adobe version, as simply changing the file-extention association in Windows for .PDF, to use Actobat 9, doesnt seem to work. At least it has no effect on the OFC PDF viewer if you try to change it manually.

The underlying reason for wanting to use Acrobat Reader 9, instead of the installed 7 version, is because we have seen Adobe the Acrobat 7 window "vanish" sometimes, when it is being called from the OFC PDF viewer. Perhaps this problem is already well known and soluable?

Thanx a lot!

Doh!

I found the awnser to my exact question in the very next thread!

Sometimes this fails as the OLF installation cannot find any of the following registry entries:
HKEY_CLASSES_ROOT\AcroExch.Document\shell\Open\command
or
HKEY_CLASSES_ROOT\AcroExch.Document.7\shell\Open\command

In the first found key it gets the .exe path and tries to locate the .exe file. If it fails to find both keys and/or the .exe file it considers Acrobat Reader not installed.

Correct, yes?

Hi Jemimus,

I guess so - but only your own testing will tell whether this does the trick for you - does it?

It turns out it doesnt. I have since tried several different combinations of keys, but I never got it to stick to the version I wanted Realiably.

In the end, we Install Acrobat 7 Standard first, then install Reader 9 on top.
OLf ill then use Reader 9 to open the files, but people can still use the 7 functionality they need.

We are about to switch to Adobe Acrobat 9 Pro for every though, this will solve the issue we had with 7
