Were you able to fix your issue ? I have also installed R 12.2 on Windows Server 2008 R2 and most of the solutions on the forum do not provide soultion for that
You can try relink FNDWRR.exe from backend and retry
- adrelink.sh force=y "fnd FNDWRR.exe"
- Retry Post Checks
This is mostly because of some OS package requirement. Please recheck all pre-reqs
