Restart Section

[AndyBoy]

Hi!

I`ve been looking at some advises here, but they didn`t help me a lot. So maybe somebody else can help me.

My installer checks the installation path, and if it is a forbidden path, it stops the installation. What i`ve been trying to do, is when the installer is stopped, it goes back to the DIRECTORY page and asks the user to select another path. I`m using this code:

Function RelGotoPage
IntCmp $R9 0 0 Move Move
StrCmp $R9 "X" 0 Move
StrCpy $R9 "120"

Move:
SendMessage $HWNDPARENT "0x408" "$R9" ""
FunctionEnd


!macro BadPathsCheck
StrCpy $R0 $INSTDIR "" -2
StrCmp $R0 ":\" bad
StrCpy $R0 $INSTDIR "" -14
StrCmp $R0 "\Program Files" bad
StrCpy $R0 $INSTDIR "" -8
StrCmp $R0 "\Windows" bad
StrCpy $R0 $INSTDIR "" -6
StrCmp $R0 "\WinNT" bad
StrCpy $R0 $INSTDIR "" -9
StrCmp $R0 "\system32" bad
StrCpy $R0 $INSTDIR "" -8
StrCmp $R0 "\Desktop" bad
StrCpy $R0 $INSTDIR "" -22
StrCmp $R0 "\Documents and Settings" bad
StrCpy $R0 $INSTDIR "" -13
StrCmp $R0 "\My Documents" bad good
bad:
MessageBox MB_OK|MB_ICONSTOP "Install path invalid! You should chose another install path."
StrCpy $R9 -1 ;Goto the next page
Call RelGotoPage
good:
!macroend

Section InstallComponents

!insert BadPathsCheck

... Some code here that installs files...

SectionEnd

The point is, that ( maybe i`m mistaken, but i keep getting errors ) Section continues to execute installation of the files, even though it shows the Directory page. Is there a way to make the Section restart, or pause?
