When I try to run the file 'msert.exe', I get the following error: The application has failed to start because it's side-by-side configuration is incorrect. Please see the application event or use the command-line sxstrace.exe tool for more detail. The appication gives an error event ID 59, but this does not help me. I have tried this on 2 different pc's, one running Win7 32 bit, and one Win 7 64 bit, and I have downloaded the correct versions each time. The same error occurs in each case. Can anyone assist?

Hi Alex, I didn't try booting in safe mode to install the msert.exe. My reason for wanting to install it was because I am recommending it to others who have virus problems. I have A/V, and no problems, so as I say, I just wanted to install it out of curiosity, and to see what it looked like and how it works. But it's not such a big deal for me. I have no currect virus problems. Thanks for your interest. I'm markng your answer as the answer for the sake of completeness. I didn't actually try these things, for reasons I've explained.
