I'm not able to understand what's wrong with the below code for jumping to particular offset if MessageBox returns IDNO.
Below code is to quit installer while IDNO is selected, but it always jumping to Goto endCurrentBlock
line
MessageBox MB_YESNO|MB_ICONEXCLAMATION "Would you like to continue installation?" IDNO +3
!insertmacro ShowStatus "Failed to install software"
Goto endCurrentBlock
Quit
If I use a absoule label for jump it's working good. What could be the reason?
Jumping by offset skips x number of NSIS instructions but
!insertmacro
is a preprocessor instruction that might expand to zero, one or several NSIS instructions.It is not recommended to combine offset jumps and
!insertmacro
because it can break your code just by changing the macro...
