I've 2 InstallScript projects creating installers for two version of my software (e.g. v1 and v2). On my old 32bit PC I had no problem in performing major upgrade (I installed the v1 than I launched the installer for v2 and it uninstalled the v1 than installed the v2 correctly). Now on my new 64 bit PC I noticed that performing the same major upgrade the process of uninstalling v1 terminates and the v2 is installed BUT in the "Control Panel" -> "Add/Remove programs" I see both the v1 and v2 icons.
Does someone know why? Does it exist a workaround?
I have the same kind of problem with IS2008. In may case this problem is for all the setups developed and already delivered. The solution seams to remove the entry manually 😞 after installation of the new major upgrade version.
The problem doesn't happen when you remove the previous setup manually from Control Pannel before install new setup....
PS: i try with IS2010 and the problem seams solved, but with IS2010 if you upgrade a setup developed with a previous version of IS the problem still remain... and you need to remove the entry manually. 😞
Your problem could be more than just an installation issue. For instance you might want to make sure you are differentiating 32bit vs. 64bit registry entries:
For instance in some situation I get my installed directory from the registry:
RegisteredInstalledDirectory = ""; if (SYSINFO.bIsWow64) then folder = "SOFTWARE\\Wow6432Node\\myCompany\\myProduct"; else folder = "SOFTWARE\\myCompany\\myProduct"; endif;
key = "InstallLocation"; type = REGDB_STRING; size = -1;
RegDBSetDefaultRoot (HKEY_LOCAL_MACHINE); if (RegDBGetKeyValueEx (folder, key, type, value, size) < 0) then WriteLog("RegDBGetKeyValueEx failed for InstallLocation."); else StringTrimRight(RegisteredInstalledDirectory , value); endif;
There are some other things you have to consider. Can you possibly run your setup.exe and generate a log?
