I am trying to install Workflow essentials to our test server for SharePoint. It seemed to install correctly, and then in the 'Workflow Essentials Component Configuration' I chose 'Deploy Workflow Essentials'. It gets to the 'Configuring Components' screen and stops at this error:
Error: Cannot add the specified assembly to the global assembly cache: Xheo.Licensing.dll.
NWS-SP3 : Error: Cannot add the specified assembly to the global assembly cache: Xheo.Licensing.dll.
I tried following instructions on this post, but the 'C:\Program Files\Common Files\XHEO\SharedLicenses\' directory does not exist (was not created during install).
Am I missing a step?
I am also having this problem. I want to install to test, but am getting hung up on this as well. Any thoughts from the gurus?
Also... I have a share licenses folder since AM and ExCM are both also installed.
The error that an assembly could not be added to the global assembly cache usually indicates that SharePoint is using the file and the installer cannot uninstall and then reinstall it.
The first thing to try is performing an iisreset to remove any handles that IIS or SharePoint may have on the assembly. If that does not work, then go to C:\Windows\assembly and right click on Xheo.Licensing and click uninstall. The same type of error may also occur for other assemblies such as SPSolutions.Common or SPSolutions.SharePoint which can be resolved the same way.
After clearing the handles on the affected assembly you should be able to deploy successfully.
You will not see the \Xheo\SharedLicenses directory after installing a recent release of the trial version of the product. It will only exist if you install the full license or if you have installed an older release which uses the trial license file.
Uninstalled Xheo.Licensing file, still get the following:
Error: Cannot add the specified assembly to the global assembly cache: SPSolutions.Licensing.Xheo.dll.
Please advise, I would really like to try this product.
Please note the SPSolutions.Licensing.Xheo.dll is a different assemby then Xheo.Licensing.dll. The same steps outlined by David will still apply. Just remove the SPSolutions.Licensing.Xheo.dll assembly from the Global Assembly Cache and retry the installation.
