<DIV>Hello,</DIV>
<DIV> </DIV>
<DIV>Starting from the silent installer, I made some slight modifications to check the OS type, as follows :</DIV>
<DIV><FONT size=2 face=Arial><FONT size=2 face=Arial>
<P><install cmd="taskkill /F /IM Firefox.exe"><exit code="0" /><exit code="-1073741515" /><exit code="128" /></install></P>
<P><install cmd='"%INSTALLER_PATH%\Firefox Setup %VERSION%.exe" -ms' /></P>
<P><install os="5\.1\.\d{4}\" cmd='%COMSPEC% /C del /Q "%AllUsersProfile%\Desktop\Mozilla Firefox.lnk"'><exit code="any" /></install> <!-- Microsoft Windows XP --></P>
<P><install os="6\.\d{1}\.\d{4}\" cmd='%COMSPEC% /C del /Q "%Public%\Desktop\Mozilla Firefox.lnk"'><exit code="any" /></install> <!-- Microsoft Windows 7 8 8.1 --> </P>
<P>At the execution I get in the WPKG log (debug option) the message : Regular Expression Syntax Error. I can't find the problem as the syntax of the os expression semms correct. Can you help me ?</P>
<P>Many thanks in advance.</P>
