Resolved Adobe InDesign won't open docs in Win 7.

I'm setting up a new desktop PC that came with pre-installed Windows 7 Home Premium, V 6.17601 Service Pack 1, 64-bit. I installed all Important updates, which included SP 2 & 3. I then installed Adobe Creative Suite CS4 Design Standard (previously run problem-free on Windows Vista).

I didn't know about de-activating the apps before installing them. I just put in the CS4 CDs and all apps installed. No hassle. All apps opened. Photoshop works fine. Illustrator wouldn't open due to plug-in problem. I ran it through the Windows Program Compatibility tool and it now works fine (Thank you!).

The problems are with InDesign and Adobe Acrobat 6 (I'll solve Acrobat later). When I try to open previously-created ID documents, I get the error message: "Cannot open xx.indd. Please upgrade your plug-ins to their latest versions, or upgrade to the latest version of InDesign ".
I can't find anything about upgrading plug-ins to latest versions. How can I do this?
I am current with all Windows & InDesign updates. I've tried running the app as an administrator and used the Compatibility Tool (I've tried using the possible different settings, each in turn, for Windows Vista, Vista SP1, Vista SP 2 and XP (SP2 and 3). I still get the same error message. I can create new InD docs, but not open any of my previous work.

I even tried changing the plug-ins in the one place I could see, in InDesign under Help > Configure Plug-ins. I tried all 3 of the possible configurations: Required, All, and Adobe, to no avail.

Can anyone help me? If this Windows forum isn't the right place for me to be, can someone please indicate a workable Adobe forum??? Thank you so much. Joan

 

It looks we goofed and installed the wrong CD. So I'm sorting that out right now. I'm hoping installing the correct CD solves all the problems. But I still needed the advice on activation, so thanks!

I will let you know. And since some others have had problems installing CS4 with Windows 7, I will let you know how it turns out when I try that!

Thanks for the friendly help!

You may recall we had erroneously installed an older version of CS. I am very happy and most relieved to report that once that was uninstalled and we installed CS4, there were no conflicts whatsoever with Windows 7.

Thanks for your help.
