I can not activate the license

If your network travels through a proxy and for some reason you can not configure it in ClickSign you will not be able to activate your license since it requires an Internet connection.In /index.php/es/manual-de-clicksign/108-configurar-un-proxy-de-salida.html the proxy configuration process is described.

As a solution to this we can generate a product license manually, you must send us the file resulting from the following process:

Abre una ventana de terminal (p.e. en menú inicio -> Ejecutar ... escribe cmd y dale a Intro o pulsa OK).
Escribe los siguientes comandos:

cd \Program Files\isigma\clicksign
ismrun RequestLicense

It will generate a file that you will have to send us by mail, and it will help us to generate a license for you.

I can not activate Clicksign Pro in Windows Vista

When trying to activate Clicksign Pro, the following error may occur:

When this happens, it is due to lack of user privileges in the operating system administration. To solve this problem, we have to execute "Options" as administrator. We will do it in the following way:

1. Access the "Options" entry in the Clicksign menu
2. Press the right button on "Options"
3. Click on the option "Run as administrator"

The following image illustrates how to do it:

What benefits does Clicksign PRO offer me, compared to the free version of Clicksign?

• When signing PDF's, no graphic mark is added to the document, only the signatures that we want to make visible. The free version of Clicksign adds the following::

• It will allow you to add more than one electronic signature to the documents. This is especially useful for signing contracts involving different parts
• In addition to PDF documents, you can sign XML, Word, JPG documents. This is especially useful if you want to use Clicksign as an intellectual property protection tool.
• You can have the SIGNLOOP function, which will allow you to define an automated signature process for documents. Once configured you will only have to worry about depositing your documents in the signature folder that you have defined. This function is especially useful if you need to sign digital invoices, both in PDF format, and in XML - facturae.

Error com.lowagie.text.pdf.PdfReader.(Ljava/io/InputStream;)V

El mensaje de error com.lowagie.text.pdf.PdfReader.(Ljava/io/InputStream;)V se debe a una incompatibilidad entre versiones de un componente de procesado de documentos PDF que se llama iText, utilizado por Clicksign y otras aplicaciones. Algunos programas instalan una versión antigua de este componente como una extensión del sistema Java, provocando conflictos con otros programas como Clicksign.

Para que Clicksign funcione correctamente, debe localizar la carpeta que contiene los componentes instalados como extensiones de Java. Esta carpeta se encuentra normalmente en C:\Archivos de programa\Java\jre6\lib\ext (depende de la versión de Java que tenga instalada y cómo la instaló) y contiene varios archivos con extensión "jar". Si alguna aplicación instaló aquí iText versión 1, uno de ellos se llamará itext-1.02b.jar, o muy similar. Mueva este archivo a otra carpeta (para tener una copia de seguridad por si quisiera recuperarlo más tarde).

Clicksign debería ahora funcionar con normalidad.

Es posible que la aplicación que instaló iText ahí deje de hacerlo. Si es así, le agradeceremos que nos lo notifique (por mail a This email address is being protected from spambots. You need JavaScript enabled to view it.) para que podamos hacer pruebas y sugerirle mejores soluciones para que Clicksign y esa aplicación puedan convivir en su sistema.

The error message com.lowagie.text.pdf.PdfReader. (Ljava / io / InputStream;) V is due to an incompatibility between versions of a PDF document processing component called iText, used by Clicksign and other applications. Some programs install an older version of this component as an extension of the Java system, causing conflicts with other programs such as Clicksign.

For Clicksign to work properly, you must locate the folder that contains the installed components as Java extensions. This folder is usually found in C: \ Program Files \ Java \ jre6 \ lib \ ext (it depends on the Java version you have installed and how you installed it) and it contains several files with extension "jar". If any application installed iText version 1 here, one of them will be called itext-1.02b.jar, or very similar. Move this file to another folder (to have a backup in case you would like to recover it later).

Clicksign should now work normally.

It is possible that the application that installed iText there stops doing it. If so, we would appreciate it if you notify us (by email to This email address is being protected from spambots. You need JavaScript enabled to view it.) so that we can do tests and suggest better solutions so that Clicksign and that application can coexist in your system.

Is the handwritten signature incorporated into Clicksign PRO?

Clicksign PRO does not add any graphic mark to the document. This will allow us to add a scanned handwritten signature, or any other representative graphic image, when we are editing the document, before converting it to PDF.

In any case, it is important to bear in mind that incorporating a scanned handwritten signature into a document has no legal value. This practice responds only to the fact of creating a psychological effect on users.

Can I use Clicksign with the Class 2 software certificate of the FNMT?

In the case of having previously installed the certificate in Windows, the easiest way is to enable the operation with CryptoApi (the natural repository in Windows).

By default it is activated, however if you want to check it and make changes you should only access the Clicksign configuration panel.

Access options from the clicksign menu.

In the Settings window, IDs and devices tab, check that the box "Use my Windows operating system certificates", in case it is checked you can see that in the list that is under "Add / Remove devices and IDs "Windows (CryptoAPI)" appears.

Can I sign invoices with the free ClickSign download?

With the free download of Clicksign you could already sign electronic invoices in PDF, but you should consider the following limitations:

• When signing the PDF, the following image will automatically be embedded in the document:

• You can only sign invoices in PDF.

• You will have to sign each invoice issued one by one without the possibility of automation.

Buying Clicksign Pro:

• You only have to worry about depositing the invoices in PDF in a certain folder, and the signature will be made automatically and transparently to the user
• You can sign XML to issue invoices according to the Facturae Standard.

Can I sign with the certificates installed in Windows?

Yes. In the installation manual we explain how.
