[Bug 45930] Microsoft .NET Framework 4.x GAC update fails for some assemblies, ' Error compiling mscorlib, Path not found. (Exception from HRESULT: 0x80070003)' (legacy GAC missing: '%systemroot%\assembly')

--- Comment #3 from Anastasius Focht  ---
Hello folks,

revisiting, still present. This is quite annoying and causes endless GAC/NGEN
update loops (going for hours).

Trigger full update of GAC + legacy location for 32-bit assemblies:

--- snip ---
$ wine "c:\windows\Microsoft.NET\Framework\v4.0.30319\ngen.exe" update
--- snip ---

Trigger full update of GAC + legacy location for 64-bit assemblies:

--- snip ---
$ wine "c:\windows\Microsoft.NET\Framework64\v4.0.30319\ngen.exe" update
--- snip ---

These finish in time with legacy GAC folder present:
