Hello everyone!
My deep apologies if this theme was posted before ( just didnt see one =S ).
When 2 days ago I installed CoD 4 and restarted, since then there appears a error window when I log in to windows telling me ( I am sorry, the screenshot wont tell you much, because it is in Czech , so I'll write it in English ) : You are missing an instalation programme for Volume . ( I didnt see any changed in Volume or about it, really. But it appears everytime and it gets my parents angry . They want to reinstall whole windows, but I wont survive the lost of 60GB of all graphic design works,projects, information gathered and favourite films ). I would want to ask , if there could someone help me with this out, please . ( P.S. I tried the : System Recover, but it didnt help. I searched internet for 2 hours and found nothing about it ='( )

Thank you for reading,

Did CoD 4 install successfully?

If so see if it appears with this tool:

If so remove the entry via the tool.

CoD 4 installed sucessfuly on all 100%, I have done Whole Campaign in Single Player and all maps in Multiplayer. Very thank you for suggestion, i tried this program and found that the window that was telling the error described more now : data1.zip and data2.zip are missing in .....instalation information/..... for Volume =S I am sorry to cause any problems. Is there any other way to recover these files or to install them by something, please? ( I have tried to search for this on internet... I apologise to tell again that i was unsucessful ='( )

Thank you for reading,
