How do I fix SIPEPS reference missing from UCMA InstantMessagingCall quick start sample

Question

I’m attempting to work with UCMA sample and came across https://msdn.microsoft.com/en-us/library/office/dn454827(v=office.16).aspx I installed the SDK from https://msdn.microsoft.com/EN-US/library/office/dn465959(v=office.16).aspx and have the pre-requisites, but for some reason when I run the sample I’m facing an error like:

{"Could not load file or assembly 'SIPEPS, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.":"SIPEPS, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"}

Is anyone aware why I might be receiving this error from the out-of-the-box sample? Know how to fix it?

Answer 1

I was able to solve this by setting the project architecture to x64. This seems to have corrected the issue.
