Starting Vuforia Studio results in an error and the following Log entry

 The HOME variable is set to %HOMEDRIVE%HOMEPATH% and if changed to the absolute path (C:/Users/username) it resets on the next start of windows.

OK, I found I work around.
Apparently the HOME variable is overwritten by my system somehow with %HOMEDRIVE%HOMEPATH% (One % missing between HOMEDRIVE and HOMEPATH). Hence, Home returns "C:/HOMEPATH%" when it is requested. When I fix that in the environment variables it works for some time after restarting the PC but then it seems to return what it was before and refuses to work. Since I do not want reboot everytime I need to use vuforia studio, I wrote a batch file which resets the HOME variable for the current session:

set HOME=%HOMEDRIVE%%HOMEPATH%
wt RefreshEnv.cmd
cd C:\users\<username>\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\PTC Inc"
".\Vuforia Studio.appref-ms"
pause

to call RefreshEnv.cmd you need to install the chocolatey package manager, but I am not sure if it is needed at all, since set HOME=... the HOME for the current cmd/powershell session. And RefreshEnv.cmd refreshes the system environment variables.

pause just keeps the cmd/shell window to see if everything worked out

    Thanks for the suggestion, unfortunately I cannot reply in the other post, so I go on here. NodeJS is not installed and, as mentioned in the other post, it might be an issue with the home variable. But I could not solve the issue using google in general, so it might be something specific to how Vuforia Studio accesses the variables (but of course I don't know).
