Deploying the Signature SDK
The SDK is installed as a set of ActiveX/COM components in the folder:
C:\Program Files\Common Files\WacomGSS
When the 32-bit version is installed on 64-bit Windows the components are installed in:
C:\Program Files (x86)\Common Files\WacomGSS
Language translation files are included with the installation so that the native Windows language is used in the signature capture dialog.
The installation requires COM registration with a number of supporting entries in the Windows registry and this is achieved by running the SDK MSI installer.
Due to the complexity of the installation process it is not practical to mimic the operations with a script but a number of options are provided for automation.
Run the installer to display the options dialog:
Options are included for Java and .Net components.
Following an installation the installed files can be seen in Common Files\WacomGSS folder, for example:
|.NET Components||Java Components||ActiveX Controls||Language Translation Files||Support Files|
To add Java or .NET components after an installation run the installer again and select the Change option in Windows to redisplay the options dialog.
In addition to the creation and registration of component files, items are added to the Windows Start menu: Wacom Signature SDK.
Command Line Installation
Use the command line to tailor the installation by using the standard Windows MSI installation application.
For example to install the minimum components for a Java application with no Start Menu options:
msiexec /q MINIMAL=1 JAVA=1 /i Wacom-Signature-SDK-x86-3.20.4.msi
A number of options are available so that specific components can be installed with or without a full SDK installation:
|MINIMAL=1||Exclude Windows shortcuts and utilities|
|JAVA=1||Include Java Components|
|DOTNET=1||Include .NET Components|
|WIN32=0||Exclude x86 components from x64 installer (by default the x64 installer will install both 32- and 64-bit components)|
|ADDPATH=Win32||Add 32-bit component folders to system PATH|
|ADDPATH=Win64||Add 64-bit component folders to system PATH|
|WIZARDSHOWWAIT=0||Disable the hourglass icon displayed by the Wizard control on the STU-430 and STU-530|
|STUSHARED=1||Use shared (non-exclusive) access to an STU tablet|
|Install the SDK||msiexec /i Wacom-Signature-SDK-x86-3.20.4.msi|
|Install the SDK with no UI||msiexec /q /i Wacom-Signature-SDK-x86-3.20.4.msi|
|Install the SDK with Java components||msiexec JAVA=1 /i Wacom-Signature-SDK-x86-3.20.4.msi|
|Install components for an IE HTML application||msiexec /q MINIMAL=1 /i Wacom-Signature-SDK-x86-3.20.4.msi|
|Install components for a Java application||msiexec /q MINIMAL=1 JAVA=1 /i Wacom-Signature-SDK-x86-3.20.4.msi|
|Create a log file||msiexec /q /l*v log.txt /i Wacom-Signature-SDK-x86-3.20.4.msi|
|Uninstall||msiexec /x Wacom-Signature-SDK-x86-3.20.4.msi|
Can I install the Signature SDK without user input?
Installer options are listed above.
The quiet option allows a UI free installation as illustrated below.
msiexec /q /i Wacom-Signature-SDK.msi
The signature of installer.msi is corrupt or invalid
This is a known issue when downloading our installers on Windows 10. You should find that the files have in fact been downloaded and that you can still execute them.
If needed the following workarounds may help:
- Turn off the SmartScreen filter temporarily in Control Panel under Security as described here.
- Add https://gsdt.wacom.eu as a trusted site in your internet options (assuming you downloaded the installers from there)
If none of the above helps please raise a Support Ticket.
Windows 7 cannot verify the digital certificate
Having installed our STU or Signature SDK you may encounter the following error message when trying to run an application which has been built with them:
Windows cannot verify the digital certificate for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.
This situation was first encountered after applying a stricter digital signing method to Wacom executables and DLLs and is mainly found on Windows 7.
The additional protection was applied to prevent the possibility of files being modified.
The error message will not be reported if Windows has been fully updated using Windows Update.
If it is not possible to apply the full Windows Update, this specific update will usually resolve the issue: KB 3153171
The update can be downloaded from Microsoft.com:
What options are there for silent installation, repair or uninstallation of the SDKs and STU driver?
STU SDK + SIGNATURE SDK
|Silent||Create log file||Repair||Uninstall||Prevent restart|
|Use /q, e.g. msiexec /q /i Wacom-STU-SDK-2.13.6.msi||Add: /l*v logfile.txt||Replace /i with /f||Replace /i with /x||/norestart|
|Silent without the "plugged in" check||Create log file||Repair||Uninstall||Prevent restart|
|wacom-stu-driver-5.4.2.exe NO_STU_CHECK=1 /install /quiet||/log log.txt||Replace /install with /repair||Replace /install with /uninstall||/norestart|
Log files are created by default in %TEMP%.
If you run the STU Driver installer while an STU is connected to the PC there is a possibility that certain registry settings may not be updated.
For this reason it would be safest to restart the PC afterwards.
