For the uninitiated…
VisualHG is a Mercurial source control plugin for MS Visual Studio
I had a bit of a problem with VisualHG a couple of weeks ago.
The overlay icons work in Visual Studio, but the context menu had no VisualHG icons and the VisualHG toolbar was inactive (had all the buttons greyed out).
Tried uninstalling / reinstalling visualhg.
Version: Visual Studio 2010 Version 10.0.30319.1 RTMRel Premium.
OS used: Windows 7 Enterprise x64.
VisualHG 1.1.0 installed.
Seems to work in VS 2008 though.
Remove all instances of VisualHG in Programs and Features.
Search the Program Files and Program Files (x86) for instances of visualhg and remove if they exist.
Search the registry for VisualHG related items (entries as well as keys). Delete them all.
Reinstall the latest version of VisualHG (currently 1.1.0).
