Thanks PhilB66, this works!

Hi

Does anyone knows of a way to disable acrobat IE intergration, so when I click on a pdf file, it will ask to save instead of opening automatically? In previous version, there is a nppdf32.dll file to delete, but for version 8, it does not work anymore.

Darn, I hate Acrobat, but the other viewers not ready to replace it.

This has to be one of the worse licensing I ever saw. I bought this software, the silver registration, and now I cannot transfer it to the new computer I bought cos my old machine is retired.

With silver registration you will get:
- Unlimited email support during the first month after the purchase
- No transfer of the program to new computers; - free upgrades are possible but not guaranteed;
no support or help with registration will be provided beyond 1 month after the purchase.

Price: 9.95 $US

With gold registration you will get:
- Unlimited email support during the first 3 years after the purchase;
- 3 year unlimited transfer of the program to new computers (if you buy a new computer you can move 5 Clicks from the old one); - 3 year free upgrades to the newest versions of 5 Clicks.

Price: 19.95 $US

Here I found one alternative freeware which does almost the same, except requiring one extra click. Darn, I will never buy from such company with absurb license.
