I recently came across this problem;
I freshly installed a new copy of PdfCreator to see that one now automagicly gets PdfArchitect. (yes I hadn’t updated a while).
All seemed to go well, until I got BSOD and a lot of stuff was wrecked.
I started in safe mode to see that my C: had 0 bytes free!
Quickly strawling through the files it appeared that PdfArchitect was trying to build a helpfile (I think it was a CHM file) and it was 40+ GB big!
Might this have tot something with the fact that I got the Help service disabled?
If so, could you please check this before trying to build the file?
