This is as expected, since the AIH is only a helper file intended to aid you in while installing Adobe products/updates.
But *why* does the installer delete itself? If I run it accidentally and decide to cancel the installation, it has deleted itself and I have to download it to again.
A helper file that deletes itself isn't very helpful.
After you download it, make a copy of it and save it to a separate folder. That's what I do.
To make a copy, do the following:
- Drag the original with the right mouse button to another folder.
- When you let go of the right mouse button, choose "Copy Here" from the menu.
The answer to the original poster's question is that this is normal and as designed.
But *WHY* did Adobe design it this way? It's simple enough to make a copy before doing the installation, but the first time it happens I have to stop and figure out if it's normal.
I suppose there might be some benefit for the average naive user, but still, most installers don't have this behavior.
