SSAS Internal error: An Unexpected error occurred (file 'pfcre.cpp' function PFCREngine::SelectCartridge)

Question

Has anyone seen this error before? If so, how did you fix it? I can't find anything on Google.

Here is what I have done:

1. I tried doing a Google search but practically nothing came up.

2. I checked all of my permissions everywhere, and from what I can tell, that is not the problem.

3. Building and deploying does not generate errors.

4. I only have errors when I try to process my cube.

Edit #1:

I have attached an image showing version information. I have never successfully processed a cube. I have been getting this from the very beginning of when I tried to process one.

Edit #2

Sorry for the delay, but I ran into some errors thanks to Windows latest update.

I am no longer receiving this error message after reinstalling everything, but this is what I have now:

I am trying to teach myself how to use SSAS for self-learning. I downloaded the database somewhere from Microsoft.

Answer 1

I had to uninstall/reinstall Visual Studio as well as SQL Server due to an update that was causing errors.

After doing so, I was no longer able to reproduce the error message in part #1; however, part #2, Login failed for user NT Service \MSSQLServerOLAPService.;28000, was resolved by doing the following:

1. Logging into SQL Server Management Studio

2. Creating a new login for NT Service \MSSQLServerOLAPService.

3. Assigning the db_datareader and db_datawriter role memberships.

After following these steps, I did not have any trouble processing my cube.

If I am able regenerate error #1 again, I will add more detail to my post, otherwise, I am problem free for the time being.
