Your XML ends with:

<InterfaceDefinition><id>Radio

so right away, I see that id and InterfaceDefinition are both unclosed.  I expect these are not root level XML tags, so you probably have more that...

Quick look at your code, your XML is missing closing tags, so it is malformed XML and as such cannot be cast to XML.

My opinion for process - install it on test, test the crap out of it, if no fault found, install on live.

As for "should" you install it?  I would.  SP2...

Alternately to Ant-Green's suggestion, if you go to the SSRS webpage, there is a download button in the top right corner (if you didn't disable it) where you can download...

To add to what Grant said, it could also be that there isn't much "new" to add.  I forget the version, but I think it was 2014 where a lot...

Basically, if you have a lot of updates on the table, you will have a lot of tempdb growth.  If the table...

My next step then would be to check the error that popped up.

The error message is:

With debugging SQL Server code, I do not use the debugger.  I've never found it to be that useful with respect to TSQL.  Maybe my code is not interesting enough...

My opinion - it sounds like strategy one is the way to go.  This lets you log all changes and you can select the changes you need to see.  What...

My next thought is that you removed something that is normally installed on a system (such as a C# redistributable package).

Might not hurt to do a repair install of the...
