addtopath function doesnt work anymore

[jweinraub]

i have used addtopath for some time, and it worked. now it seems it stopped working. did some new MS patch cause this not to work?

if i manually add it, the remove it from path in the uninstaller works fine. the adding doesnt!

Section "MainSection" SEC01
SetDetailsPrint textonly
DetailPrint "Installing My Special Software..."
SetDetailsPrint none
SetOutPath "$INSTDIR"
; WTF - not working - and it should - really - it should !!!
Push $INSTDIR
Call AddToPath
Push "PATH"
Push $INSTDIR
Call AddToEnvVar
