Installing GPG4Win on a laptop with a high resolution shows blurred installer text.
It seems GPG4Win uses NSIS for the installer. If yes, the fix is then just to add this:
enable support for high DPI resolution
ManifestDPIAware true
Requires NSIS 3.x. See http://nsis.sourceforge.net/Reference/ManifestDPIAware for reference.
While we are at it, if the installer uses not already Unicode this should be enabled with this:
make it a Unicode installer
Unicode true
See http://nsis.sourceforge.net/Reference/Unicode for reference.
