hello,

your cdf file does not store the definition for x in your case.

Use therefore

g = Manipulate[
   Plot[Sin[i t], {t, 0, 10}, ImageSize -> Scaled[x]], {i, 1, 5},
   Initialization :> {x := .5}]

or use

x:=.5
g=Manipulate[Sin[i t], {t, 0, 10}, ImageSize -> Scaled[x]], {i, 1, 5}, 
SaveDefintions->True].

to safe any definitions associated to expr.

Best,

Christoph
