I created a pure Universal Installer project and a 5.x project. Both are installing only one file. If I do an installation with the generated 5.x project installation the dialoges are shown in a normal speed like it does with InstallShield MulitPlatform 5.03. If I do an installation with the generated Universal Installer installation and the new dialoges the performance is worse. You can see how the different controls and the background are painted. I tried it with a bundled 1.3.1_06 JVM and a 1.4.2_05 JVM. The result is the same. The installation with the 1.4.2_05 JVM is even a little bit slower.
The installation is build on Windows XP SP1 (german) with JDK 1.4.2 and is running on Windows XP SP1(german).
I am using the normal settings in Tools / Options.
I am using Version 10.02 B20608 of InstallShield X Premier Universal Installer.
I tried the two installations on different machines (Windows 2000 SP4 german, Windows XP SP1 german, Windows XP SP1 english) and had on all systems the same performance difference.
The new dialogs are much slower than the 5.x dialogs. I can see the whole drawing of the dialog (new dialog).
The both appended .avi files will shown the performance difference.
