VideoStudio :: Installation Of X5 Stops With Fatal Error

I have been using Ulead VideoStudio / Corel VideoStudio since the 4SE version and made all upgrades, up to X4.On April 1, 2012, I purchased then the UG from VS X4 Pro to VS X5 Pro and downloaded the software through the link provided by Corel.

I start the installation, enter the S/N of X5 and X4 (because I purchased an upgrade).But installation always stops with an error message at the following step: "Please wait while we configure Microsoft Visual C+++ 2005 Redistributable"

The error message is: "1: ALLUSERS property is not 1 - this MSM cannot be used for a per-user or fallback-to-per-user install".

What I already tried so far...I already uninstalled VS X4 and used the "VS_Cleanup", but the error persists. Meanwhile, I contacted Corel support, and they recommended to uninstall Microsoft Visual C++ and then to re-install it. I followed their instructions and uninstalled all instances of Microsoft Visual C++ and then re-installed the latest version, i.e. Microsoft Visual C++ 2010 SP1 (x64).However, the same problem persists.

Meanwhile, I tried many other approaches: I moved the installation file (.exe file) to the desktop and tried the installation from there, I tried the installation as another user (equally with administrator rights), I tried to install under Windows Safe Mode (this failed, since some necessary drivers or software was apparently not loaded), removed any remaining traces of VS X4 manually and made a registry clean up, etc.Note also that all latest updates of Windows and related software are made.

I also re-downloaded the installation file, in order to make sure there is no problem with a corrupt installation file.

Video standard: PAL/SECAM, manually selected during the installation process.
