Artifactory retrieve artifact action failing with permissions error

any idea why I would get this?
The get source from subversion works just fine.

Based on the Action Configuration ("Retrieve the /client/%CLIENT_PATH%/InstallCusmod-%CUSMOD_COUNTRY%-%CLIENT_VERSION%.exe artifact from the Cusmod repository to c:\temp"), you entered "c:\temp" for the "File Name" property of the action.

I assume "c:\temp" is an existing directory? This would cause an UnauthorizedAccessException.

Try setting it to "C:\temp\file.exe" or something.

Have you done any perf. testing beweetn sqlite and sqlce 4? I run a website with very fast response times using sqlite but the write operations are defintely blocking to all readers. the site is about 80% read and 20% write. I was contemplating moving over to sqlce as our number of visitors have increased - lack of support for windows 8 has me a bit worried.
