Hi Rarisso,
Error code 1618, also known as “MSI Installation Already In Progress”, occurs when the Microsoft Installer is already in the middle of another installation:
- A previous installation is still running
- The computer needs to be rebooted to complete a previous installation
- There are two sessions running the MSI installer on the machine
To fix this error, you can try the following:
- Wait for the other installer to finish
- Reboot the computer to flush out the previous installation
- Open the Task Manager, go to the Processes tab, and find msiexec.exe
- End any msiexec.exe processes that are running
- Disable any antivirus or security software temporarily during the installation process
- Delete the contents of the “%TEMP%” folder on your computer
- Use the Windows Installer Cleanup Utility to remove any previously failed installations
Also, there is no Run button in RealityCapture. Did you mean Start? How did you install RealityCapture?
