Error installing 1.2.0 on win 7 64-bit

I was looking all the web for a solution for this:

When trying to install the 1.2.0 version I get an error message: "The filename, directory name. or volume label syntax is incorrect".

I've tried to install it in xp-sp3 compatible mode, and I'v tried to stop and run again the spooler (as advised in the forum: http://www.pdfforge.org/forum/help/5766-pdfcreator-windows-7-64-bit-does-not-install).

Any ideas?

SOLVED.

The problem was in my operating system and using non-english letters for my folder names.

After renaming my folders installtion was swift.
