Having paged through the pdfforge.org website, I do not find any minimal system requirmements definitions for PDFCreator. Specific unanswered questions:
Will work on which of Win95 (95/95a/95 OSR x?), Win98, Win98SE, WinMe, WinNT4 (x86? Alpha?) (SP which?), Win2k (SP which?), WinXP x86_32 (SP which?), WinXP x86_64 (SP which?), Vista (x86_32 and/or x86_64?, builds which?), Wine (versions?), ReactOS (versions?)?
Requires how much RAM?
Requires how much HD?
Requires VB runtimes? Which ones? Where does one get them?
Requires PDF, PPD,
And I'm sure there are additional specifications and requirements which aren't listed.
