Windows Server 2008 R2 Issue

Hello, I need help with windows server 2008 r2. The problem is that any 32 bits application is running, when I try to run a 32 bit aplication I get an APPRASH message. Reading some post I found that "ServerCore-WOW64 is not found" I have try to run some commands like: 1. dism /online /get-features | findstr /i WOW64, Result: Nothing is returned appears to be disappeared. Same I run this: 2. sfc /scannow Result: Beginning system scan. This process will take some time. Beginning verification phase of system scan. Verification 100% complete. Windows Resource Protection did not find any integrity violations. 3. dism /online /enable-feature /featurename:ServerCore-WOW6432 Result: Deployment Image Servicing and Management tool Version: 6.1.7600.16385 Image Version: 6.1.7600.16385 Error: 0x800f080c Feature name ServerCore-WOW6432 is unknown. A Windows feature name was not recognized. Use the /Get-Features option to find the name of the feature in the image and try the command again. The DISM log file can be found at C:\Windows\Logs\DISM\[login to view URL] Note: The day before yesterday, everything was running fine but "suddenly" something was wrong.. Please help me if you know how to solve this issue Best Regards!
