Let me fix it myself
To resolve this issue, you can reset the registry settings to their default settings. To do this, follow these steps.
Click the Startbutton and type regedit in the Search box Right-click Regedit.exe in the returned list and click Run as administrator Browse to the following registry key: HKEY_CLASSES_ROOT\.exe
With .exe selected, right-click (Default) and click Modify� Change the Value data: to exefile Browse to and then click on the following registry key: HKEY_CLASSES_ROOT\exefile
With exefiles elected, right-click (Default) and click Modify� Change the Value data: to "%1" %*
Browse to and then click on the following registry key: KEY_CLASSES_ROOT\exefile\shell\open
With open selected, right-click (Default) and click Modify� Change the Value data: to "%1" %* Close the Registry Editor and restart your PC
Just check to see if those reg keys read like that – if they don’t, make them as above.
