craig i've fixed it and got it working,
so so so good
from the sandbox i went
- right click on sandbox
- run from start menu
- programs/system tools/control panel
- launch the default programs tool
- change adobe to be default
then to test i opened two explorers, one in sandbox and one outside of sandbox.
- in the sandbox adobe acrobat reader launches when i click on a pdf
- outside of the sandbox ecopy pdf pro launches when i click on pdf
so great made my day, this should work / launch pdfs from acrobat reader from email client as well, however haven't tested just yet.
i'll give it a go and give you feed back.
P.S. is there a way to make this particular registry change stay even after i delete content of the sandbox.
thank you in advanced.
