Impossible to connect to SSAS using http://localhost:1080/datapump/msmdpump.dll

Question

Hello,

I installed SSAS 2017 on windows 2016 but I can't find the way to connect to using IIS.

I keep have the next error message :

==================================

===================================

File system error: The following error occurred while writing to the file 'MSOLAP ISAPI Extension: C:\inetpub\wwwroot\datapump\msmdpump.dll : Access is denied. .
Internal error: An unexpected exception occurred. (Unknown)

Can anyone give an idea please?

Best regards,

Daniela
