Hi,

I am getting this warning (see below) when using DMS in an automation script. There seems to be a version mismatch. The file used is located here:

C:\Skyline DataMiner\Files\

What could be the cause for this?

The Interop dlls are used to directly call our native processes (Interop.SLDms.dll => SLDMS) using the COM interface.

It is usually not recommended to interface with a DataMiner like this however. We would recommend to use the SLNet API (SLNetTypes.dll) to communicate with a DataMiner.

However the issue you're seeing here looks like a mixup of .NET Framework 4.0 vs .NET Framework 3.5.

The Interop dlls still reference .NET Framework 3.5 so not having this installed might be the cause of this issue.

Thank you for your help! I guess the best solution is to implement a workaround that does not make use of the older dll.
