This problem came up on my laptop today and I have found a solution, at least on mine. I was getting the exact same error as above (with different memory locations) when I tried to start Distiller (Acrobat 7.0). It had worked fine for years. On mine it was limited to my specific user account. I could run Distiller fine from the Administrator account. I also created a new standard user account to test with and it ran fine from that one as well. But it wouldn't run from my personal account. So I knew it was something with that specific account.
To make a long story short, it ended up being a corrupt cache. You can find the cache in the following location:
C:\Documents and Settings\[your user name]\Application Data\Adobe\Acrobat\Distiller 7\
What I did was just rename the old cache folder and let distiller recreate it. That fixed it. Good luck.
