Thank you so much for your prompt reply.Whilst on the subject, I must inform you that a couple of days ago, my Computer went off due to power failure. I have, since then run cd\ chkdsk c: /r to repair any corrupt files. This morning, I have received errors not only as mbae64 being the faulting module name but also from wshom.ocx version 5.8.7601.18283 [ Faulting module path ~ C\Windows\ System32\wshom.ocx ] for the same Application error in WScript. Summing up, I don't think MBAE, alone is the only cause of this application error. However, I wish to inform you that I have again run Chdsk to repair corrupt files. So far my computer is Okay. I personally feel, perhaps the power outage could be the main reason why these files have become corrupt and leading to errors. I shall give you further information should the errors come again. Thanking you. Anshi.
