BUG #: 409361 (SQLBUDT)



SYMPTOMS
Consider the following scenario. In Microsoft SQL Server 2005, you run, import, or migrate a Microsoft SQL Server 2000 Data Transformation Services (DTS) package. The SQL Server 2000 DTS package contains an instance of the Analysis Services Processing task. In this scenario, you receive the following error message:

WORKAROUND
To work around this problem, click Start, click Run, type the following command, and then click OK:

regsvr32 &quot;C:\Program Files\Microsoft Analysis Services\Bin\msmdtsp.dll&quot;

Note Include the quotation marks because the path contains spaces.

After you click OK, you receive the following message:
