When you invoke SAS Enterprise Guide 4.1, the following error message might appear:

[mscorlib]

Unknown Error (-1).

This error message can appear when SAS Enterprise Guide cannot access the sdsconfigv4.xml file because the file is damaged. The path for the sdsconfigv4.xml file is C:\documents and settings\your-user-id\application data\sas\sas directory services.

To correct the problem, rename the sdsconfigv4.xml file to sdsconfigv4.old, and then restart SAS Enterprise Guide. You can also correct the problem by copying sdsconfigv4.xml from another machine to replace the damaged file.
