Editing PDFs with PDF-XChange


For more information on connecting PDF-XChange to buildagil, see the following article: Editing PDF Documents with Local Programs.


Editing in PDF-XChange

PDF documents from buildagil can be edited directly in PDF-XChange without having to download them. When you save, the changes are automatically saved as a new version in buildagil, ensuring that the documents are always up to date.



Multiple people cannot edit PDF documents at the same time. To prevent conflicts between document versions, the document can be checked out. While the document is checked out, other users cannot edit it.



As long as a document is checked out, other users cannot edit or delete it. For more information, see the following article: Editing PDF Documents with Local Programs.

Troubleshooting


If the following troubleshooting steps do not resolve the issue, please feel free to contact Support.



Troubleshooting PDF-XChange When It Won't Start

When opening PDF documents, PDF-XChange does not launch; instead, the error message "No program was found to open the PDF document" appears.



This can be resolved by installing the new version of the buildagil Opener. For more information, see the following article: Installing the buildagil Opener. If the error persists, check the "Installed Apps" section in Windows Settings to see if an older version of the Opener is still installed. You can uninstall it.

Troubleshooting the "Invalid Parameter" Error Message

When opening PDF documents with PDF-XChange, the error message "The document cannot be opened. Error [System]: Invalid parameter." may appear. In this case, the document cannot be loaded.



This can be resolved by deleting existing connections to SharePoint under "File / Open." These connections prevent documents from being opened from buildagil.



Alternatively, you can delete the document history in PDF-XChange. To do this, select the document in question under "File / Recent Files / History" and delete it by clicking "Remove."

Troubleshooting: The buildagil login screen appears instead of the document content

When opening a PDF document with PDF-XChange, the document may not load correctly, and the buildagil login window may appear as the PDF content instead.



This can be resolved by enabling the SharePoint extension in the PDF-XChange settings.
