Selected Test Results

What works

It was possible to install the tool after installing .NET 3.5 via winetricks.

Nexus Mod Manager loaded fine and tried searching but crashed with "The given path's format is not supported". Log file showed "NotSupportedException while getting files from: Z:\var\lib\bluetooth\00:26:83:2F:88:E7"

Removed Z: drive from winecfg, ran search and found applications ok, then closed application. Re-enabled Z: drive, loaded application, started fine.

The game selection screen was then shown.

What does not

After selecting the required game, a loading splash image was shown, but the application then crashed, erroring with:

The UriTemplate 'Sessions/?Login&username={p_strUsername}&password={p_strPassword}' is not valid; each portion of the query string must be of the form 'name=value'. See the documentation for UriTemplate for more details.

This prevents any further progress.

See also this thread where someone else has reported the same problem:

Noted also this thread where it has happened to a Windows user and was resolved by removing and re-installing .NET:


What was not tested

Unable to get login form to appear, so unable to test any mod functionality.

Crash Scanning Z: drive in wine.
by Travis Greenman on Monday December 16th 2013, 13:09
You have to stop the scanning process of the other games it doesn't instantly find a match to before they reach the Z: drive in wine otherwise it'll crash when it hits files with characters that are invalid in windows, like ones with : in them.

Error from hitting a file with an invalid character:
NotSupportedException while getting files from: Z:\run\xdmctl\dmctl-:0

The given path's format is not supported.

RE: Crash Scanning Z: drive in wine.

I got past the scanning problem by opening up winecfg and removing the Z / drive, can add it back after.

It is very good that you have gone to such great lengths as to fix and compile some dlls yourself. But it looks like you're violating the GPL license by posting the DLLs without providing the corresponding source code.

Check out the section 4 of the GPLv2 license:
