Thank you very much for the update amate2.
However, please let us know what is the exact and complete error messagein the pop-up that actually highlights the .DLL files that are corrupted. It would help us troubleshoot the issue related to those specific .DLL files and also, to know the particular programs they are related to.
In addition to that, I would suggest you to run a System File Checker (SFC) scan to check for any files corruption:
- Go to Start, click All Programs and open Accessories.
- Right click on Command Prompt in the Program list and then select Run as administrator. If you are prompted for an administrator password or for confirmation, type your password, or click OK.
- In the Command Prompt, type the following command, and then press ENTER:
sfc /scannow
