I use an scriptbased setup. After starting the setup an ask on dialogs some things,
i ask, if the user would deinstall the existing version of my program.
if i realize, existing program was installed with Install Shield 5.5, I deinstalled with:
stringA = WINDIR + "\\IsUn0407.exe";
stringB = " \-fC:\\ProgrammPath\\Uninst.isu";
LaunchAppAndWait (stringA,stringB,WAIT);
because this code doesn´t work under InstallShield 6.3 (the help-Files didn´t tell help me realy, also the Help-Guids), so I try next:
if the program was installed with the InstallShield 6.3 an I try to deinstall with:
stringA = "\"" + DISK1TARGET + "\\setup.exe\"" + " -uninst";
LaunchAppAndWait (stringA, "", WAIT);
it doesn´t work. However, the error-Messages show, that the program try to write and open the setup-file on the DISK1TARGET-place again. I try to change the Deinstall-path, but i can´t do it.
Thank you for your help !
