Having trouble building firmware - tup error

When i run make, i get the following error:

tup error: Unspecified output files - A command is writing to files that you didn’t specify in the Tupfile. You should add them so tup knows what to expect.
– Delete: %SystemDrive%\ProgramData\Microsoft\Windows\Caches\cversions.2.db
*** Command failed due to errors processing the output dependencies.

my Tupfile.ini is blank and I also tried changing the file extension of cversions.2.db to cversions.2.db111 and I still got the same error.

Any ideas on how to solve this?

Delete your build folder and the .tup folder, then try again?
