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.

Google Chrome: Security

At one of my client sites they are constantly doing security changes, and for some reason recently several users complained that they could not access Oracle PeopleSoft via the Chrome browser.  It was returning

Error 312 (net::ERR_UNSAFE_PORT): Unknown error.

After doing some trusty Google Searches, I found this simple solution:

Right click on your Icon (shortcut) to run Chrome and go to properties, and on the Target line add the parameter:

--explicitly-allowed-ports=xxxx,yyyy,zzzz

where xxxx, yyyy and zzzz are ports that you want to allow.  This will solve the problem.
