Visual Studio 2013 - All forms shortened by about 15% on install

Hi Experts
I have an app which installed fine on W7 for a while.  Now suddenly, the bottom edge of each form in the app has been moved up cutting of the bottom of the control at the bottom of the form.   Thinking it may be resolution based I changed the resolution.  Each time the form appeared the same but changed in proportion to the resolution, so it wasn't that.   I am using Setup Factory9 as an install package and I could go back to the solution and create the installation again bit that would be a pain..  Anyone any ideas?

If you just copied a form (app) across to this PC does it still show the 85% form or the correct 100% form ?  (Maybe it is nothing to do with the installer but a system setting on the PC)

Sounds like a resolution issue.

Try to change the AutoScaleMode property of the Form to None.

Followed Andy's advice and copied the solution across to that PC, ran the app from the Release folder and found the same problem, proving it was the app

Followed Eric's advice and checked the system font - enlarged to 125% -  put it back to 100% and the forms were correct.

So assume must now go back to the solution and change the autoscalemode property back to None and then go through creating the install package again.

Also making sure to change to none in future solutions

Thanks both for the help

>>go through creating the install package again

With my installer I just copy the newly compiled files to the source folder and hit recompile.  No need to go through a lengthy procedure of creating a fresh installation.
