Error 1 while building in 8.2

Question

This error below occurs when I build. I try to put a path into the destination path but it does not get saved. I have tried the entry in the destinations folder entry and the Application information. I have copied the path and also selected the path from the browse icon but neither work. <Not a Path> is always the default and cannot be changed.
Any suggestions as to the cause? 
Error 1 occurred at Invoke Node in ABAPI Save Libraries New Dest.vi->ABAPI Dist Build LLB Image.vi->ABAPI Copy Files and Apply Settings.vi->EBEP_Invoke_Build_Engine.vi->EBUIP_Build_Invoke.vi->EBUIP_Build_Rule_Editor.vi->EBUIP_Item_OnDoProperties.vi->EBUIP_Item_OnDoProperties.vi.ProxyCaller
Possible reason(s):
LabVIEW:  An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @.

This happens when you're building an executable?  The default build path for executables should be C:\Users\**Username**\builds\**ProjectName**\**ApplicationName**
Often, repairing your install can fix strange problems like this.  Just go in like you're going to uninstall LabVIEW, but instead repair it.
Additionally, what do you have as the input to the invoke node you mentioned?
