    Please launch Regedit, search for HKEY_CLASSES_ROOT\MSOLAP.5

    If there is a MSOLAP.5 key, delete it and restart the GW service to see if it works. (Please backup your registry keys before deleting)

Have just found that a windows patching was implemented yesterday. does this related?

 

i have tried

regsvr32 -u "C:\Program Files\Microsoft Analysis Services\AS OLEDB\130\msolap130.dll"

 

regsvr32  "C:\Program Files\Microsoft Analysis Services\AS OLEDB\130\msolap130.dll"

 

to unregister the dll and registered again with no luck

 

Thanks
