thank you to your answer.
In cmd line that works like wthis:
start soffice.exe --invisible "macro:///Standard.Module1.SaveToPdfA1("C:\wamp64\doc.docx")"
all files/folders are in all control to my user windows( and im admin)
so, sofficework, but not this command if its call by php with library phpdocx
hmm, very strange.
do you have some ID?
Thank you
