I'm trying to install MSXML versions 3 & 4 from InstallScript.
With version 3 I try:
LaunchAppAndWait(INSTALLDIR ^ "msxml31100.exe", "", WAIT);
It starts to install and then says that another installation is in progress (true, because this is a sub install), and I have to quit.
With version 4 I try:
LaunchAppAndWait(INSTALLDIR ^ "msxml4.msi", "", WAIT);
This does nothing!
I've read that: "Windows Installer service does not allow multiple setups to run simultaneously". But then how do I do these sub installs?
Any help would really be appreciated.
