I purchased this about a week ago and it seemed pretty stable - but I ran into one problem which is pretty annoying. Whenever I launch Excel 2013, I get an error: "Excel.Exe - Bad Image - c:\windows\system32\dlumd11.dll is either not designed to run on Windows or it contains an error..."
I was on with tech support for awhile - they had me verify I had the latest graphics drivers and the latest display link software which I do.
I also found this article on Microsoft's support site:
http://support.microsoft.com/kb/2813143 - but this didn't yield any results.
For me so far, it's only Excel that crashes. If I start it in safe mode, it's fine. Or if I simply un-install the display link software - that works to, but then I can't use my two external monitors. Very frustrating! If anyone has an suggestions, please let me know. I would like to get this resolved.
BTW, I'm running windows 8 Pro on a Sony Vaio 13" Pro. Great laptop -everything works perfectly except this display Link Adapter and the only issue was with Excel -and I can't stop using Excel.
