Windows Installer tries to install Adobe over and over again at boot up

My version of Adobe Acrobat Pro 6.0 (I know it is not supported by Adobe) installs sufficiently so that I can use it (mostly). However the request for install the program is still in the Windows Installer. So each time I boot, I need to cancel the install of Adobe since it doesn't do anything, even when I let it run to completion.

How do I find and rid myself of the command that tries to install Adobe each time I re-boot the system???

Windows Vista 64 bit, running on an Intel duo-core system with 4GB RAM.

Thanks

I had a similar thing when every time I ran a particular program it asked me if I wanted to install it. I straightened things out by using this KB utility. It might work for you too:
