  • Question

  • Hello,

    First time on this forum, and just trying to create an Excel add-in for the first time ever and very frustrating to run into this issue at this stage. For starters, Excel IS installed (from a 365 account) and using VS 2017 (so I'm guessing they should be compatible?) and running both without problems. I created an Add-in with the default options and when selecting Start I get the error window:

    "The application associated with this project type isn't installed on this computer. You must install the Microsoft Office application that is associated with this project type."

    Selecting ok prompts another dialog window warning that "There were deployment errors" and asking if I wanted to continue.

    Selecting yes, shows yet another error window: "Unable to start the program 'C:\Program Files\Microsoft Office\root\vfs\ProgramFilesX64\Microsoft Office\Office16\excel.exe'. The system cannot find the file specified"

    The location the error makes reference to doesn't exist, at least not the Office16\excel.exe part. Excel is located under C:\Program Files\Microsoft Office\root\Office16

    Anyone has any pointers as to how to bypass this error and get VS to understand where Excel is?

    Thanks.

  • For anyone interested, after much googling and trying different things, I was able to resolve this issue by changing  <TargetOfficeVersion>15.0</TargetOfficeVersion> to <TargetOfficeVersion>14.0</TargetOfficeVersion> in the project's .csproj file...

    Doesn't make a lot of sense to me, but it works...

  • Do not start Excel like:

     'C:\Program Files\Microsoft Office\root\vfs\ProgramFilesX64\Microsoft Office\Office16\excel.exe'

    But start excel like 'cmd.exe /c start excel.exe'

    Let the system find out which Excel is installed and were ;-)
