I successfully installed archicad 22 but on opening I get the error "Error while opening the file: C:\Users\Username\Graphisoft\TWData\TWDataOptions.xml". I'm running it on Windows 10. Please help.

Hi Syl Kat,

This is an error message when ARCHICAD cannot access all of its folders / files.

Possible reasons:
1. ARCHICAD was installed with a different user on the same machine.

Since many folders are put to the current user's folder, I recommend to reinstall ARCHICAD with your own user.

2. A 3rd party monitoring application (antivirus, backup) is blocking ARCHICAD's files/folders.

Put all GRAPHISOFT related files and folders on exception list in these applications.

3. User does not have enough permission on certain GRAPHISOFT folders.

Check if on all GRAPHISOFT related folders your user has full Read/Write permission.

Kind regards,
