Hi All,

Our application interacts heavily with Visio Interop both through COM from a separate .NET process and when running as an Add-in. Most of the errors visio throws out are useless as a message, but we've come to understand roughly what circumstances cause them to happen. In this case we've encountered an error very occasionally, and have no idea what it means.  

We were calling IVPage.SetResults, and it has thrown out the error code -2032466642, "Failed to update subscriptions". In this case the code was running from within a COM Add-in.

Could someone please explain why Visio is doing this. At least could someone tell me what subscriptions this is trying to update? I wondered if it was related to Office 365, but apparently this is just happening on a standard Visio 2013 Pro installation.

Searching for information on this error has thrown up almost nothing, and the couple of posts I can find are unrelated to what we're doing. Any information on this would be appreciated.

Thanks,

Will
