Hello HornKiel,
The error is observed because the installer is trying to access a folder with limited permissions. You would need to run the installer with administrative rights. Please try the following steps and let me know if the issue persists :
1. Run the command prompt with administrative rights.
2. Type the following command to run the installer and create install log :
For msi:
msiexec /i InstallerName /L c:\logfile.txt
In case there is still a problem with the installer, send me the logfile.
Thanks,
Richa
