I am trying to make a custom toolbox with documentation following the steps on https://www.mathworks.com/help/releases/R2018a/matlab/matlab_prog/display-custom-documentation.html. However when trying to build the search database I got the error that "Error using builddocsearchdb (line 32) There is no installed product with this help location. Documentation that is not associated with a product will not be displayed in the help browser."
Looking into builddocsearchdb and executing the commands myself, circumventing the check on line 32 gives a "Could not write search database." error.
The example provided by the builddocsearchdb help with the upslope toolbox (https://www.mathworks.com/help/releases/R2018a/matlab/ref/builddocsearchdb.html) gives the exact same errors.
Any ideas what's wrong? The error did not happen with the earlier 2016a version, but it is present after my upgrade to 2018a.

The "builddocsearchdb" function requires an absolute path to the "html" folder for the third party toolbox.
If it does not receive the absolute path (e.g. "html" instead of "C:\MATLAB\MyToolbox\html") it will throw this error.
Using
>> builddocsearchdb("C:\MATLAB\MyToolbox\html")
instead of
>> builddocsearchdb(".\html")
may resolve this issue.

Had the same problem in 2018a and 2017b. Solution steps: 1) Add documentation directory to path - showed validation error in info.xml 2) Fix the validation error 3) builddocsearchdb works!

Thanks! I'm not sure if this also works, but in the end it turned out that even though I had full read-write access, the problem went away simply by running in administrator mode.
