Unfortunately, that's all the details there are. I got the dialog box and it said as I reported. It specifically said that I had files missing from my OS, which seems very unlikely -- more likely is that it expected to find XP, which I don't use. As soon as I saw the dialog box, I got rid of everything. I wish I could be more help, but you can bet I'm not going to try it again.....
Your colleague's report is a bit thin on actual details
