Adagio may be using BOE .NET SDK in which case no you cannot mix them.
So if you have Sage which I believe uses CR for VS version 13.x
CR 2011 uses version 14.0 runtime
BOE .NET SDK version 14.1 runtime.
I don't know what SDK Softtrack uses.
I suggest talking to Softtrack and asking them what version of the SDK they are using. We've done updates to CR for VS runtime so it could simply be they or Sage need to update their applications to the same version of runtime.
Could simply be a mis-match in the runtime their applications are based on.
You need to talk to them to get more details.
Programs and feature should tell you what versions you have installed.
