Cause

• This type of error can occur when you have use the Microsoft Software Installer (.MSI) package version of the GeoStudio installer. 
• Using the MSI installer package requires the latest Microsoft Visual C++ Redistributable(s) installed on the computer as well.

   • If you are using the GeoStudio MSI installer package on a 64-Bit operating system, you need to install:

     • vc_redist.x86.exe
     • vc_redist.x64.exe
2. Download the necessary Microsoft Visual C++ Redistributable(s) installer(s) from the following link:
