"This file is currently not available for use on this computer": SOLUTION

[Shari]

Hi,
if you get the following error message on startup and/or accessing
rules (Ctrl-R):

This file is currently not available for use on this computer.

most likely in a dialog with a stack trace looking similar to the
following:

at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.FileStream.Init(String path, FileMode mode, FileAccess
access, Int32 rights, Boolean useRights, FileShare share, Int32
bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String
msgPath, Boolean bFromProxy)
at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess
access, FileShare share)
at SimpleFilter.FiltersObject.LoadFromFile(String sFilename)

and you have a networked "My Documents" folder and the error pops up
when you are disconnected from the network, then you can use the
following workaround:

Simply create a REG_SZ under HKCU\Software\Microsoft\Fiddler2 with the
name UserPath and the value of some accessible local folder (e.g. C:
\local\Fiddler2\).

Happy fiddling.
