Hey Richard,
Good Day.
I still facing errors during upgrade see the below steps which I have performed.
1) First I tried to install separately GP 2016 16.00.0814 patch and that is showing below error:
"The upgrade patch cannot be installed by the windows installer service because
the program to be upgraded may be missing or the upgrade patch may update
a different version of the program. Verify that the program to be upgraded exist
on your computer and that you have the correct upgrade patch"
2) Then I drop the GP 2016 16.00.0814 into the updates sub folder then I run the installation program and its
successfully installed but when I run GP utilities to update the database that is showing below error.
"Error message when you access Microsoft Dynamics GP Utilities: "There was a
problem ascertaining product version information. Microsoft Dynamics GP Utilities
will now exit. Check DUinstall.log for more information"
Note: I renamed the GP2015 R2 installed folder name as Microsoft Dynamics _Old then I choose the
same directory to install the GP 2016 R2.
Thanks
