Cannot install Reporting Extensions on SQL 2012

Hello,

i had a AX2012 System on SQL 2008 R2 (All on one box). I upgraded to SQL 2012 and AX 2012 R2. After that Reporting didn't work anymore.

I decided to uninstall Reporting Externsions and wanted to reinstall it, but now i cannot reinstall the extensions - the setup routine doesn't recognize that there are the reporting services installed.

I manually installed CLR types and SQL Management objects, both for SQL 2008 r2 - but still facing the same problem.

What else could solve my issue?

Thank you,

Thomas
