"_LogicLib_Label_61.5

Could someone please tell me why this:

${If} ${FileExists} "$INSTDIR\${PRODUCT_NAME}.exe"

gives me this:

Error: could not resolve label "_LogicLib_Label_61.5" in install section "MainSection" (0)

?

Thank you very much.

You don't have an ${EndIf} (or not enough of them). The label that can't be resolved is where the block of code to be skipped when the file doesn't exist should end.

Of course! Thank you so much!
