Problem

This error is shown when a VSS provider blocks (or vetoes) the creation of the VSS snapshot. This may be caused by

  • Installing a new 3rd party VSS provider
  • An existing provider becoming corrupted

Solution
Re-register the VSS components
Copy and paste the following lines into a DOS batch (.bat) file and execute:
cd /d %windir%\system32
net stop vss
net stop swprv
regsvr32 /s ole32.dll
regsvr32 /s oleaut32.dll
regsvr32 /s vss_ps.dll
vssvc /register
regsvr32 /s /i swprv.dll
regsvr32 /s /i eventcls.dll
regsvr32 /s es.dll
regsvr32 /s stdprov.dll
regsvr32 /s vssui.dll
regsvr32 /s msxml.dll
regsvr32 /s msxml3.dll
regsvr32 /s msxml4.dll
vssvc /register
net start swprv
net start vss
a snapshot and can be due to:

  • installing software which installs its own VSS provider,
  • existing VSS provider component has become corrupted.
