Adding to VS2010's Help Viewer 1.0 works as expected, and it's awesome.
But when calling the batch file (with argument h2) to add the help files to VS2012's Help Viewer, I get an error.
I haven't altered the bat file yet, so the command looks like this:
HelpLibraryManagerLauncher.exe /viewerVersion 2.0 /catalogName VisualStudio11 /locale en-us /wait 0 /operation install /sourceUri "%CD%\NatchOS.Documentation.msha"
First I get a box about untrusted content etc, which asks me to continue.
Then I get messagebox with the title "Help Content Manager" and the following text:
An error occurred while updating content on your computer: Could not find file 'C:\ProgramData\Microsoft\HelpLibrary2\Catalogs\VisualStudio11\Incoming\<some-guid>\NATCHOS_DOCUMENTATION.mshc'
Notice the underscore in the filename, as oppossed to the dot.
The HelpLibraryManagerLauncher is version 220.127.116.11
