Hi,

I am getting a PathTooLongException and the suggested fixes don't work (partially because the path is a really long path in GAC).
Setting LongPathsEnabled=1 doesn't seem to have an effect (not even after a reboot).

NCrunch has encountered an internal error: System.Exception: System.IO.PathTooLongException: The path 'C:\windows\assembly\GAC_MSIL\System.Configuration\4.0.0.0__002400000480000094000000060200000024000052534131000400000100010007d1fa57c4aed9f0a32e84aa0faefd0de9e8fd6aec8f87fb03766c834c99921eb23be79ad9d5dcc1dd9ad236132102900b723cf980957fc4e177108fc607774f29e8320e92ea05ece4e821c0a5efe8f1645c4c0c93c1ab99285d622caa652c1dfad63d745d6f2de5f17e5eaf0fc4963d261c8a12436518206dc093344d5ad293\System.Configuration.dll' could not be processed because it exceeded the maximum allowed length of 259 characters. Try setting your 'Workspace base path' setting closer to the root of your disk, or set the registry entry 'SYSTEM\CurrentControlSet\Control\FileSystem\LongPathsEnabled'=1

Hi, thanks for sharing this issue.

There are three situations where you can see this error:
1. When the path is too long, and the registry setting has not been set
2. When the path is too long, and the registry setting is set, but the .NET platform is still kicking up a PathTooLongException when NCrunch tries to process the path
3. When the path is too long, and the NCrunch engine cannot successfully read from the described registry value

Long file paths are somewhat messy when it comes to .NET as a whole. They are getting better, but they only work when every part of the underlying platform supports them. It may be worth checking to see whether there are any other hoops you need to jump through to enable them on your machine (such as a group policy).

With that said, I've found it better to avoid long paths wherever possible. It's not clear to me why this assembly has been installed to such an intolerably long path. A simple option may be to simply copy it out of the GAC and reference it from a different path instead.
