Issue description
When you install Archicad 28 update 1 you may receive this warning message: Windows cannot find 'C:Program'. Make sure you typed the name correctly, and then try again.
Solution
This warning message is appearing by error and there is no issue with your Archicad 28 installation.
The warning only appears on Windows when using the auto update feature in combination with starting the installation from Archicad. In this case, the update is successful but the installer is not able to automatically start Archicad at the end of the installation, which triggers the error.
This issue was addressed in a software update. To resolve this, make sure to download and install the latest Archicad 28 build for Windows.
