Hi @Balders,


This error message may be caused by cached data being corrupted during the installation of Alteryx Designer.


Could you please try the following :


1. If any version is currently installed then, uninstall Alteryx Designer on the machine

2. Look for one of the following folder:

- for admin version: %PROGRAMDATA%\{3D5F2072-D5E9-45AE-AAB0-61A9BCC23F16}

- for non-admin version: %LOCALAPPDATA%\{5BBE09C3-F621-4856-B450-5D132FEAA6C5}

3. Rename folder to "%currrent_name%.old" (ex: {3D5F2072-D5E9-45AE-AAB0-61A9BCC23F16}.old)

4. Run installer again (AlteryxInstallx64_2018.3.4.51585.exe or AlteryxNonAdminInstallx64_2018.3.4.51585.exe)



Kind regards,
