Unusable K2Studio.Config file: A corrupt K2Studio.Config file has been known to cause this error (or one very similar). If repairing the registry does not solve this problem (i.e. the solution described in this KB article), you may need to reinstall K2.net Studio in order to re-establish a correct K2Studio.Config file.

Note: Personalized settings and recent solution lists in K2.net 2003 Studio will be cleared, as these settings are stored in the registry under the same key that will be deleted. However, the corrupt value may be anywhere in the Registry Key, so deleting the entire Key is the easiest way to resolve the exception. K2.net 2003 Studio will recreate the Registry entries when it is opened again.
It is recommended that the attached VBScript file be used to delete the Registry Key. Only use the manual method of editing the Registry if you are experienced in doing so.
