How can I repair Error 16820 (using Windows 7)?

I purchased and installed an upsell of Adobe Creative Suite 5.5 Design Standard. While I was waiting for the suite CD to arrive, I downloaded the Trial Version. At the time I ordered I asked the man I was talking to how to install it and he said "just install it." Supposedly I did not need to uninstall anything. Originally InDesign, PhotoShop and Adobe Professional 7 had been purchased separately. Now I am running both versions. Since installing it, I can no longer View PDFs on the web. (I can't download my UPS bill; I can't download anything from YouSendIt; I can't download my Amazon invoices. As a printing operation, this is very disconcerting.

I have done everything I know to do. After two days of fighting with the problem, I even checked my hard drive for disk errors. There were no problems. I've followed instructions regarding plug-ins, enablements, etc. etc. I clicked on Adobe_com and got an error message saying Mandatory download. When I tried to download the update I received an Error 16820 message. A search of google said to download Error 16820 repair utility. After attempting that I learned that ErrorEnd is not compatible with Windows 7.

Now I'm reading that Adobe does not support multiple versions of Acrobat or Reader on the same machine. I had no problems with this when I was using Adobe Professional 7 with Adobe Reader. Some material we receive can only be printed from Adobe Reader. My original thought was that it was a software conflict which brings me back to the question: Should I delete the older versons of InDesign, PhotoShop and Acrobat Professional. Since the suite is an upgrade, I thought I would have to keep the earlier versions.

I have an invoice and two YouSendIt books waiting to be downloaded and I can't resolve this problem! I was hoping Adobe had a support email for their customers who bought new equipment-- especially to the tune of $899!

Yeah I know this topic is a year old and odds are the problem is most likely fixed, however, the answer to this question is relatively simple. Uninstall everything, run Adobe Cleaner and install CS5.5 from the Disc, install any and all updates and your problems should solve themselves.

Because it is obvious that is a software conflict and nothing else.
