My trial has expired, but I'm loving the product, and purchased it this morning.

As I'm still learning about memory dumps and looking at the data I'm a little stumped at this error message. One of our clients were having issues, so I thought I would ask for a memory dump from them - they opened task manger, rightclicked on the application and selected "Create Memory Dump", they then sent this file to me - 1.5 GB in size.
Opening the .DMP file in Visual Studio 2017 worked just fine, I had no issues. However when I try to open this dmp file with .net memory profiler I get this error:
"The operation failed with the following error: No .NET runtime found in the process"
before I got this error it was having trouble finding a dll (mscordacwks.dll) on the MS symbol servers - looking at the version of the dll it was asking about (and some googling) I found that this file is a Silverlight v5 dll and the file could be found in "C:\Program Files (x86)\Microsoft Silverlight\5.1.50907.0" however the file wasn't in there - I selected "mscorlib.dll" by accident from that folder, and since then I have been getting the above error message and no prompt for the dll.
So how can I analyse this DMP file in the application (and not VS2017), and in future, how do I get actual dump files from clients that will work?
Doing the above "Task manager > Create Dump File" worked when I did this on my Local PC with no issues.
Many thanks for any help / pointers about this.

Edit 1: Just found this like - https://memprofiler.com/online-docs/def ... pfiles.htm
The screen shot on that page about the ".net data access library" is the one I'm talking about. After selecting an invalid file at this point, I'm no longer getting the prompt but it comes up with the error message I mentioned above "No .NET runtime found in the process". How can I reset it to prompt me for the file?
Edit 2: I searched the clients machine at the silverlight folder mentioned, and that file doesn't even exist there. Currently no idea where to get the file from, can't find it via googling either.
