In Event Viewer appears such message (maybe this message can help to resolve this problem):

Activation context generation failed for "c:\program files (x86)\microsoft sql server\120\Tools\Binn\managementstudio\CopyDatabaseWizard.exe".Error in manifest or policy file "c:\program files (x86)\microsoft sql server\120\Tools\Binn\managementstudio\CopyDatabaseWizard.exe" on line 8. The value "1.0" of attribute "version" in element "assemblyIdentity" is invalid.

Source: SideBySide

Event ID: 63

Hmm. Anybody have a suggestion for David?

Thanks!

Your information is not concrete are you just worrying because you saw event viewer and there was some message it in. Please tell us error, if any, you are facing have you ever used copy database wizard ?

Good day David

As Shanky mentioned we need more information before we can recommend anything. right now we can not recommend anything! but only point some general information. we only know that there are logs about an error but we have no information of the source for this error. (1) Can you monitor what are you trying to do when you get this error? (2) what version and edition are you using?

Basically as much as I can see, this file CopyDatabaseWizard.exe, is used in several actions like: in upgrade installation, using the Copy Database wizard, etc. This is not a new file for SQL 2014, but there were issues with it in the CTP version as you can see here.

You can find the file in this locations for example depending on your Server version:
C:\Program Files (x86)\Microsoft SQL Server\120\Tools\Binn\ManagementStudio
C:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE

** Several sites reports this file as Trojan horse virus. I have no knowledge regarding this! but as we have no information on the source of your log error, you should checks this as well.
