sign pro PDF Version 4

FAQs

---Installation and start-up---

Installation failed

Run the installer on Win 10 where sign pro pdf has not been previously installed. The installation wizard fails with the log file showing:

Error 0x800700e8: Failed to wait for child to connect to pipe.
Error 0x800700e8: Failed to connect to elevated child process.
Error 0x800700e8: Failed to actually elevate.
Error 0x800700e8: Failed to elevate.

Solution

The error sometimes occurs due to anti-virus software. Please check if anti-virus is active before running installer. If so, disable before re-testing.

The error has been encountered when running Avast Antivirus.
When the antivirus is disabled the installer works as expected.

The installation of sign pro PDF failed

Occasionally the sign pro PDF installer may fail with the following message:

The installation of sign pro PDF failed.
The installation failed due to one or more problems. For more information, see the file: log file

On examination of the log file error code 0x800f081e or 0x80070002 is found when installing NDP462-KB3151802-Web.exe, which is a Web installer for .NET framework 4.6.2.

sign pro PDF needs the .NET framework 4.6.2 and tries to install it. If it is already installed or a later version is present then the above error may occur.

Workarounds

  1. Install the .NET framework 4.6.2 before installing sign pro PDF.
  2. Uninstall it (if already installed) and then re-install it after sign pro PDF if the sign pro PDF installer fails to install it.

---Licensing and usage---

Why is the default Licensing Mode not restored after uninstall/reinstall?

The default Lite License is not restored after applying an Enterprise license, then uninstalling and reinstalling the application.

Solution

The license is stored with other settings in a configuration file user.config in the user's hidden AppData folder, for example:

C:\Users\John.Smith\AppData\Local\Wacom\Sign_Pro_PDF.exe_Url_igtiubau4uwtwrhohq5zt1pkyv0afibn\4.1.3.0

The application is designed to retain the user settings (including the license). This avoids settings being lost when a different user uninstalls then reinstalls the application

The signature registration component is not licensed

After upgrading from sign pro PDF version 3.5 to version 4 the following error message may appear when trying to capture a signature:

The signature registration component is not licensed

This situation can occur if a licence key for version 3.5 had been installed in the registry and has subsequently expired. Its location is as follows:

HKEY_LOCAL_MACHINE\SOFTWARE\{Wow6432Node\}Wacom\signpro\Licence

Version 4 might detect the licence, try to use it and recognise that it has expired.

Solution

Remove the 3.5 licence key from the registry
Uninstall version 3.5 (if still installed)
If necessary, uninstall and re-install version 4.

Signing failed

When trying to sign a document the following error message may appear:

Signing failed
No capture service available. Unable to find a functioning digitizing
tablet or any other device for capturing signatures.

Solution

Ensure that a signature device is connected to the local PC, i.e. the computer on which sign pro PDF has been installed.

  • If using an STU device (e.g. a 430 or 540) then make sure that the STU driver is installed.
  • If using a DTU or similar Wacom pen display tablet the Wacom tablet driver must be installed.
  • If using a Wacom-supported touch-screen device the Wacom Feel Driver must be installed.
  • If using a device which is not operated using Wacom hardware such as a touch-screen digitizer or pen then a special RTS licence for sign pro PDF must be obtained from Wacom Sales.

If sign pro PDF is being accessed on a remote server via RDP then third-party USB forwarding software must be used to forward the pen data over the network - the only way round this is to use a signature pad which operates serially - there are two possibilities:

  • STU-430V
  • STU-540 (which can be switched into serial mode)

For more information please see our FAQs on: 430V Serial Set-up and 540 Serial Set-up

Display the name and reason for signing on the PDF

Is it possible to include the name and reason for signing in the signature image which is captured on the PDF?

Answer

Unfortunately this is not possible with version 4 of sign pro PDF.
It was possible with version 3.5 which can be downloaded here
