Invalid class string (Exception from HRESULT: 0x800401F3 (CO_E_CLASSSTRING))

Hi and welcome to another post from Non-Stop BizTalk!

Had a virus or a trojan a couple of days ago on my Windows Server 2003 test machine. After I performed a scan-clean procedure, I luanched BIDS (Business Intelligence Development Studio) to work with the Adventure Works Cube Project sample. When I tried to browse the Adventure Works.cube, the browser failed to load and the exception Invalid class string 

(Exception from HRESULT: 0x800401F3 (CO_E_CLASSSTRING)) was thrown.

I followed the steps available here, which is re-installing the 

Microsoft Office 2003 Web Components, and this solved my problem.

Cheers

Failed to load application [DBName] due to incompatible versions. Please upgrade the application to version 3.0.3917.0.

Hi,

When you apply SP1 for PerformancePoint Server 2007 you need to upgrade your application databases, for them to work properly with the upgrade, or otherwise, you will keep getting the error message in the event viewer "Failed to load application [DBName] due to incompatible versions. Please upgrade the application to version 3.0.3917.0." and the applications created prior to the upgrade won't show up in the Planning Admin. Console. To upgrade the application databses run the Planning Server Configuration Wizard, then select Upgrade Databases in the step Add/Remove Services as the following screenshot ilustrates:





In the next step "Upgrade Databases" select Upgrade Application Databases and proceed with the configuration procedure.

I hope this was useful!
