Personally, I have found the messages of support from scientists everywhere to be truly heartfelt, and I would like to highlight some of the community initiatives I’ve seen here: We also want to use our platform to highlight the response from the scientific community. As then it may work, but I still had to load it at every start manuall, I created a link to C:\Program Files (x86)\Mendeley Desktop\wordPlugin\Mendeley-1.19.5.dotm in the startup-folder (find your Word Starup-Folder: ).still had the warning though, that the Add-In wasn't trusted so also added C:\Program Files (x86)\Mendeley Desktop\wordPlugin\ as trusted location ( ).But still got the "Run-time error '429' ActiveX component can't create object", so debugged the VBA of the plugin and saw it happened when trying to create the object for the COM server and as describes that can happen with a not properly registered application, found in the Mendely installation folder the MendeleyWordPlugin.exe and did a "C:\Program Files (x86)\Mendeley Desktop\MendeleyWordPlugin.exe /regserver" - after that the plugin starts working for me.so I followed Weixin Huang 's instruction to load the plugin manually.Installation of Plugin via Mendeley Client is not supported.
