This error indicates there was a Windows Installer related problem (Soluto uses Microsoft's Windows Installer to setup on the computer). The error could be caused by a number of issues, please go through the steps below.
First, make sure you are not running the install from Windows Safe Mode, as this method is not supported.
1. Run the Soluto Uninstall Cleanup Tool:
Download and run the Soluto Uninstall tool, which will remove any Soluto leftovers from previous installation. The tool will run in the background and popup a small notification in the System Tray when it completes:
Please reboot the PC after running the uninstall tool.
2. Delete Downloaded Program Files and Temporary Files:
Most often, deleting temporary files will resolve the issue. Please follow these steps:
Go to Computer / My Computer and right click on your system drive (usually C), select Properties.
Click on Disk Cleanup and make sure that "Downloaded Program Files", "Temporary Internet Files"and "Temporary Files" are checked as shown in the screenshot below (please note that this operation will not delete the files you've downloaded to your "Downloads" folder):
3. Install the latest Windows Installer version from Microsoft's website:
This step is relevant for Windows XP and Windows Vista users, as Windows 7 & Windows 8 comes pre-installed with a newer version of Windows Installer.
