Dual boot – Win XP / Win 7 – activation problems

Question

Here's the scene:
1/ Have Xp installed and CS4 running fine... (used to have CS3 as well but there was a mobo problem and CS3 now gives an activation error message. Too much of a hassle to reformat and reinstall... yada, yada, yada.)
2/ Just installed Win 7 to test as a dual boot option and installed CS4 fresh. PS and AI both give me a "Licensing for the product has expired" message with no options. There are no other activations, meaning no alternative on another system or laptop, etc.
Is there a work around or do i have to do a completely fresh install? Meaning, deactivate CS4 in th XP boot and then reinstall CS4 in th Win 7 boot?
TIA...

Answer 1

Here is the answer without having to join the site where the answer lies. The stuff that was removed by me were things that I felt were inappropriate for an Adobe Forum. They do not affect the ability to perform the fix:
So you installed Adobe Creative Suite  Master Collection or any of its other applications, and now  you can’t even open up any of these programs. You’re probably receiving the now  semi-infamous “Licensing for this product has  expired” pop up error.
This error  will more than likely affect the use of the following programs:
Adobe InDesign CS4
Adobe  Photoshop CS4 Extended
Adobe Illustrator CS4
Adobe Flash CS4 Professional
Adobe  Dreamweaver CS4
Adobe Fireworks CS4
Adobe Contribute CS4
Adobe After Effects CS4 
Adobe Premiere Pro CS4
Adobe Soundbooth  CS4
Adobe OnLocation CS4
Adobe Encore  CS4
Don’t worry, because some guys over  at who knows where got the fix that will save you many hours of headaches. The  problem lies within the “amtlib.dll” file in each of the CS4 application  directories. However, downloading a simple fix and updating each of the files  with a newer one can solve this problem.
Step 1:
Download this file it includes both  amtlib.dll files the second file(64bit) is only  to be added to photoshop (64bit)  folder the rest use the regular amtlib.dll file:If you download this file skip to step 3 !
Code:
http://www.megaupload.com/?d=WZKC1K7Q
other  files for step 2 using the " removed by si conehead ".
Personally i like doing in manually its only like 17 files you  need to change:
Code:
removed by si conehead
Step 2:
Run the (removed by si conehead)  and allow for the file to be copied  over to all the directories. This should fix all your problems.
If the above two steps didn’t work, try the  following:
Step 3:
Search for:  “amtlib.dll” in the Adobe folder C:\Program Files\Adobe\.
Step 4:
Replace all the “amtlib.dll” files in  each of the Adobe folders with the file in the downloaded fix.
ONLY
do the following steps if the previous steps  didn’t work for you.
Step 5:
Go to  C:\Windows\System32\drivers\etc, open the “hosts” file there with Notepad.
Step 6:
Add the following  lines at the end of the file:
127.0.0.1  localhost
127.0.0.1 activate.adobe.com
127.0.0.1 practivate.adobe.com
127.0.0.1  ereg.adobe.com
127.0.0.1 activate.wip3.adobe.com
127.0.0.1 wip3.adobe.com
127.0.0.1  3dns-3.adobe.com
127.0.0.1 3dns-2.adobe.com
127.0.0.1 adobe-dns.adobe.com
127.0.0.1  adobe-dns-2.adobe.com
127.0.0.1 adobe-dns-3.adobe.com
127.0.0.1 ereg.wip3.adobe.com
127.0.0.1  activate-sea.adobe.com
127.0.0.1  wwis-dubc1-vip60.adobe.com
127.0.0.1  activate-sjc0.adobe.com
::1 localhost
Step 7:
Go to C:\Program Files\Common  Files\Adobe\Adobe PCD\cache
and delete the file “cache.DB” 
Step 8:
Enter a new  serial number for the applications and open up any Adobe Creative Suite  program.
Now everything should be working fine.
