For anyone else reading this with problems activating PP2000 I have found the issue (at least in my case) is that the keygen usage instructions that come on the discs with the clones are a little misleading.
This info has already been mentioned by Betty in previous posts in this thread but I thought I'd make it crystal clear.
For example in my v22.14 disc the instructions read:
This KeyGen is a activation tool for PP2000-21.14 / 2114 / V1.8.2 (same tool for LEXIA3)
1. Custome code: 001
2. Version Number: PP2000-21
*Attention: Please DO NOT iuput Other Version number such as PP2000-21.14, PP2000-V21 !!!!!
3. Input the right identifier of your pc number & Server request code that you get in the PP2000 activetion page
Now reading this you would most likely enter PP2000-21 as the version number in the keygen right?
Well that would cause the keygen not to work giving an error 11 invalid activation error each time.
Similarly if you enter the version that is displayed in the PP2000 activation details page where you see the 'PC number' and 'Server request code' (PP2000-22.14 in my case) it will also not work.
The actual version you need to enter in the keygen is the version displayed on the PP2000 activation page WITHOUT the .XX subversion.
So for me that was PP2000-22
This drove me crazy for almost 2hrs so thought I'd save anyone else the trouble.
Also if you are on Win7 Microsoft has made an 'XP Mode' Virtual machine available for download for free (will check for valid Win activation). This is a self contained WinXP image that runs in MS Virtual PC so it saves messing around with VM's and loading XP - It's all done for you.
Install and use Windows XP Mode in Windows 7
