When starting the Application Designer, Data Mover, or Configuration Manager, it will automatically error with the message(s):

• This application has failed to start because the application configuration is incorrect.
• The application has failed to start because its side-by-side configuration is incorrect.

PeopleTools 8.50 is developed using Microsoft Visual C++ 2005.  Microsoft changed the way it bundles the CRT (C Run Time) files, and if these fails are not present you will see the above error messages.  There is a section in the Installation Guide – Task “Verifying Necessary Files for Installation on Windows”.

For PeopleTools 8.50, the easiest fix is to navigate to your PS_HOME\setup\vcredist directory and run vcredist_x86.exe.

For PeopleTools 8.51, navigate to your PS_HOME\setup\psvccrt directory and run psvccrt_retail.msi.
