Symptom; the program can't start because ouilibnl.dll is missing from your computer, try reinstall the missing file to fix the problem
Possible manual solution for you 'handyman-fixers' out there;
The file Ouilibnl.dll is a part of "Desk 365" , which is classified as malware by many providers ("Elex.Desk365", "AdWare.D365", "PUP.Optional.Desk365.A"), typically distributed by way of a thirdparty installer or toolbar browser highjacker. It is not recommended that you attempt to reinstall this file on your computer, which is also why we do not offer this file for download.
As far as I can tell, this is technically not a virus, but it does exhibit plenty of malicious traits. The industry generally refers to it as a “PUP,” or potentially unwanted program. Malwarebytes Anti Malware, mentioned above, can remove this.
If you get an error for this file at Windows start, remove the autostart entry.
How to remove the Startup entry:
Win XP, VISTA, 7: Press "Windows"-key + "R" to bring up the "Run" dialogue. In "Run" dialogue type "msconfig" and hit Enter Under the tab "Startup", uncheck any boxes relating to these files. Win 8: Press CTRL+SHIFT+ESC at the same time to bring up the Task Manager. Under the tab "Start-up", uncheck any boxes relating to these files.
Should you not find any references here to the Ouilibnl.dll, try the Microsoft program Sysinternals Autoruns. Available for free at: http://technet.microsoft.com/en-US/sysinternals/bb963902.aspx
