Customer's FAQ
Q: What version should I choose? A: Just run DEMO version and it will print it. Briefly, if you can open PDF file, but can not print, edit etc, get the restriction remover version. If you can't even open file, get n-clients version. Q: I've tested GuaPDF on my file, but got only blank pages (or some errors) A: It is DEMO version, it can process small files only. Q: Ok, but how can I sure the full version will work on my file? A: If DEMO parses your file with no errors, the full version will work fine. Q: Ok, how long will it take? A: Restriction removal is instant (may be few minutes on very large files). To estimate key searching time, run DEMO version (and divide it to the number of your PCs). Q: Are non-standard security handlers supported? A: No, please run DEMO to make sure your file is supported. More questions and answers you'll find in the included documentation. | ||
