On a newly installed Symantec Management Agent (SMA) with a freshly installed x64 Inventory Solution plug-in, any attempt to execute a standalone inventory eg.:
InvSoln.exe /fi or /dhi or /dswi will fail with the error message below.
Configuration for Inventory task "Collect Full Inventory" is not found.
Task should be executed at least once prior to running it using InvSoln.exe
IT Management Suite (ITMS) 8.0 Hot Fix (HT) 4.
A fix for standard (not server) inventory is available in ITMS 8.0 HF5 and in 8.1 versions.
As a workaround the corresponding standard inventory policy must be executed first.
