In case it helps, here's my Windows "shortcut"

C:\Windows\System32\cmd.exe /k java -jar C:\Users\gary.grosso\Downloads\PDF=
Box\pdfbox-app-2.0.0-RC1.jar PDFDebugger && exit

It's possible you only need to add ".\ " in front of " PDFDebugger" (or wou=
ld that be "./"?) but the shortcut is much handier IMO.

Thanks guys.=20
Also, I meant to add in my last email that I was not able to find the PDFDe=
bugger.
My best effort was:

   C:\Users\ntiskt02\Downloads>java -jar pdfbox-2.0.0.jar PDFDebugger Renew=
alFaxCover_MN_MP.pdf
   no main manifest attribute, in pdfbox-2.0.0.jar

Am I missing something?

Likely won't be possible. What I do is to run the WriteDecodedDoc command l=
ine utility and then do the changes manually. However you need to understan=
d the PDF operators and the sizes of the content streams should not change,=
 i.e. all object positions must stay the same.

Alternatively, get Acrobat Professional.
