Excel VBA: Getting error 1004 using APPLICATION.RUN to run a macro

Question

    
I'm getting a 1004 error when my ADDIN tries to launch a macro already in a workbook .
The macro resides in a workbook (on disk before it was opened in this session) and the addin opened the workbook, updated some data fields in spreasheets in the workbook and now is trying to cause the macro, already in that workbook, to execute as though
the user had opened the workbook, made the changes, and clicked the button connected to that macro.  What the addin copied into the workbook was data in cells that the macro uses for inputs to its calcualtions.
The error reads: "The macro may not be available in this workbook or all macros may be disabled"
The command in question is in an ADDIN and its code is effectively:
v2="Taxplan Template 1.17.xlsm!SUMMARIZEYEAR
Application.run v2
...etc
Immediately upon executing "Application.run " it jumps to the on error location.
Taxplan Template 1.17.xlsm is open and accessible (the addin has just copied data into it and the macro is to update a summary based on that updated data) and it contains the macro Summarizeyear which has no arguments and is not private. 
If I set a breakpoint in the addin right before the "Application.run", stop the addin and manually run the macro it works fine.  It begins like:
Sub SummarizeYear()
Sheets("Summary").Select
...etc
If I manually open the workbook  Taxplan Template 1.17 I can run the macro SUMMARIZEYEAR without issue.
Macros are enabled in Excel.
Probably not pertinent but I've used the same style of code with .xls workbooks in the past without a hitch, this is the first instance where I used it with .xlsm format workbooks.

Thanks

This line is not quite correct,
v2="Taxplan Template 1.17.xlsm!SUMMARIZEYEAR
it is missing the closing double quote, also since your file name contains a space, I would also enclose it in single quotes.
