hi, I don't know what's the problem on my OS, but I receive this dumping with default options

Resolving member refs: 507 -> 507 defs, 0 refs
Error: failed to open mgd resource file ''
Error: failed to read expected 3036 bytes from mgd resource file ''
Could not create output file, error code=0x80004005

Here's my command typed in prompt:

C:\Program Files\Red Gate\ANTS Profiler>ilasm /dll /out=test.dll/res=RedGate.Lic
ensing.Client.dll.res RedGate.Licensing.Client.dll.il

Thanks
