NAV2015 Could not load file or assembly 'Microsoft.MSXML'

Hi,

We recent installed NAV2015 (CU63) on a new Windows server (VM). In f.e. invoices we get the error message "Could not load file or assembly 'Microsoft.MSXML'". I see that in directory c:\Windows\system32 and in c:\Windows\syswow64 the msxml3.dll and msxml6.dll are installed. I have register both dll's, but still I get the error message.

I have used a gacutil tool to add MSXML again. This solved the problem.

Try putting it into Addins folder and Service addin folder , restart the service and then check.

Thanks for help!!

I have copied the files from C:\Windows\SysWOW64 to C:\Program Files\Microsoft Dynamics NAV\80\Service\Add-ins

msxml6.dll
msxml6r.dll
msxml3.dll
msxml3r.dll

And I have copied the files from C:\Windows\System32 to C:\Program Files (x86)\Microsoft Dynamics NAV\80\RoleTailored Client\Add-ins

Restarted the Dynamics services, but still get the error message.

Also I deinstalled Dynamics and installed again, but still the error message appears.

Ideally it should come, at what time its showing this error?

You should install (or repair) MSXML (and remove it from add-ins folder again).
