i uninstalled sdk 1.0 and installed the 101 from scrach but it wars the same see pic.
i think the installer search for cygpif2designer.msi but in the package is cygpif2designer_1.0_715
i am testing...
sdk101.JPG 62.8 K
i changed the file name in the dir
C:\Cypress\EZ-USB FX3 SDK\1.0.1\updates
this is probably the cache location for the installer.
from cygpif2designer_1.0_715.msi to cygpif2designer.msi
and the install runs completly.
but maybe all my faults ? never now
