August 24, 2020 at 5:33 pmlorenzolaporta96 SubscriberHi, I' m not able anymore to launch workbench 2020 R1.nwhen I try to do that, the start window appears and the messages on the low withe bar flow untill it shows: initializing project. nAfter this it just closes without showing any error message. nthis is happening since I did the last windows update but I'm not sure it is the cause, the student licence should last 6 months so it should be still valid.nI hope someone can help me!nRegards,nLorenzo La Portan

August 25, 2020 at 10:02 pmtsiriaks Ansys EmployeeHi Lorenzo,nThat's not the same directory.nThe %appdata% would lead you to something like C:\Users\\AppData\RoamingnThis is where ANSYS store config files. nYou can just copy-paste the commandnmove %APPDATA%\Ansys %APPDATA%\Ansys_oldnhopefully renaming this folder (resetting the config) would help.nIf that doesn't help, try reinstall all prerequisites by going to folder (default) C:\Program Files\ANSYS Inc\v201\prereq , and manually run all the installers here one-by-one. Make sure they are all successful. You can skip the opencl and MPI related ones. You may need to reboot after this.nThen, run the Product & CAD Configurations GUI with 'run as administrator' -> Configure Products & CAD -> Select all to configurenDoes this help ?nThanks,nWinn

August 28, 2020 at 10:43 pmtsiriaks Ansys EmployeeCan you post the screenshots of the error when running these 3 installers ? Please post them inline with text.nAlso, in CMD Prompt window, enter this commandnappwiz.cplnthis will launch Programs and Features window. Please scroll to see all of the currently installed Microsoft Visual Studio C++ and take screenshot of this. Please make sure it shows the build version number.n
