#13 error when running backup on windows server 2000

[Mat_J]

I have tried to run msbp.exe on a SQL 2000 server running windows 2000 server SP4, with .NET Framework 2.0 SP1. The following simple test was to backup the existing model database on the default instance (the system has two instances) but it errors with:

J:\MDR-Prod-Backups\MSSQLCompressedBackup>msbp.exe backup "db(database=model)" "local(path=J:\testbackup.bak)"

The specified module could not be found. (Exception from HRESULT: 0x8007007E)
