The software was already installed, but after updating to Windows XP SP3 I couldn't start Stylus Studio without the Windows Installer dialog appearing. The dialog only has a Cancel button. Clicking the Cancel button does nothing except disable the Cancel button. There is no close box in the title bar. I looked in the Task Manager Process tab and the CPU was 0.000 for both Stylus Studio and Windows Installer. What is interesting is that the Window Installer program name is regsvr32.exe. That program registers DDLs and ActiveX controls in the Registry.
Before I re-installed the Visual Studio C++ libraries, the Windows Installer dialog appeared while Stylus Studio was verifying the installation. Afterwards, the Windows Installer dialog appeared at the beginning of the installation.
Every time I tried to uninstall Stylus Studio, I couldn't because I got that same Windows Installer dialog. I had to use Revo Uninstaller to uninstall Stylus Studio.
Stylus Studio is the only application that I'm having this problem with, but I'm sure it's a Microsoft problem because every thing was fine until updating to SP3.
I have attached a JPG with screen shots. I searched for an installation log, but I couldn't find one.
4. Uninstalled Microsoft Office 2003 using Windows Install Cleanup 4.71.1015.0 msicuu2.exe.
5. Disabled ZoneAlarm Security Suite 7.0.473.0.
6. Disabled Uniblue SpyEraser 220.127.116.110.
But Microsoft's regsvr32.exe is hanging or waiting or whatever. It's purpose is to register dynamic-link libraries and ActiveX controls in the registry.
I don't know what to try now, other than a complete clean install of Windows XP and then endlessly go through Windows Update, re-install all my software and go through all their updates too. This will definitely be a last resort. :)
