I've tried a couple of obvious things - I disabled the plugin, ran word to let it do its registry things, then re-enabled the plugin and tried again. Same result. There's a pause while it loads the HPE Content Manager Plugin, then boom. Word still runs, but with the plugin disabled. As far as I can see, the actual ECM client runs ok (although I haven't tested it a lot)
I've attached a screenshot.
Has anyone else seen this? I've tried installing with and without the VS runtime re-reqs, I've also tried updating with Patch 2, no luck. All of the instructions that I see online for dealing with an error like this presume that it's an application that I'm packaging myself, not one that I've downloaded and installed.
I'll wait and see what comes back before sending this to HP support.
