Impossible to install PDFCreator

I have a real problem installing PDFCreator from version at least 1.0.4. I have tried the install on a number of computers running variously Win XP, Vista, Win 7, Win Server 2003, 2008, 2011 (not server versions of PDFCreator) and no matter where I try to install I get

"Error creating registry key:
HKEY_CURRENT_USER\Software\PDFCreator\Profiles\High compression (small file sizes)\Printing\Formats\PDF\Compression

RegCreateKeyEx failed; code 1021
Cannot create a stable sub key under a volatile parent key."

I have been trying to install with each release and get the same error.

This has to be a problem other people have encountered. It happens every time  I try an install on any platform.

Doesn’t the developer listen to this BLOG


we havn´t run into this issue yet and most other users don´t seem to have this.
Do you install with additional parameters?
Did this happen for recent versions (1.6.x, 1.7.0)?
